Magnets and Plants

Broad Question

What will affect plant growth?

Specific Question

How does magnetism affect plant growth?


It is hypothesized that six magnets will make the plant grow the most.

Rationale:I say that because magnets have elctro fields of energy, and that energy could potentially be used to make the plant grow more. Since many plants such as beans and radishes have small amounts of metals such as Iron and magnesium. I think that plant will be attracted to the magnets that causing the plant to grow bigger but will be tilted at an angle towards the magnet. That means that the plant may not be as “strong” or stable as the other test subjects but it may be larger in length. I base my hypothesis on this. “It seems that scientific findings from Belyavskaya N.A. Biological effects because of strong magnetic field on plants (2004) Advances in Space Research, thirty four (7 SPEC. ISS.), show that there is an instantaneous effect on the growth of plants and magnetism with in the living plants”. “In 1862, Louis Pasteur discovered that magnetism affects plant growth when he was experimenting on the basics of fermentation. It starts with the thought that we have a tendency to will do it and the thought that we have a tendency to will do it together.”

The average growing length, for the Radish plants with no magnets was 5 (cm).The average growing length for Radish plants with 2 magnets was 4 (cm). The average growing length for the Radish plants with 4 magnets was 4 (cm). The average growing length for the Radish plants with 6 magnets was 5 (cm). The Radish plants with zero magnets in their presence grew the longest.


The experiment was setup to test whether Radish plants with magnets in presence while growing was to affect the length they grew. The results showed that the Radish plants with zero magnets in their presence grew on average , the longest. The average growing length for the Radishes with zero magnets in their presence grew on average one centimeter longer. The average growing length for the Radishes with 0 magnets grew to 5 (cm). The average growing length for the radishes with 2 magnets grew on average, 4 (cm). The average growing length for the Radishes with 4 magnets grew, 4 (cm). The Radishes with 6 magnets on average grew, 4.5 (cm).

The experiment question, was whether magnetism affects plant growth. The experiment did answer the question. The trials showed magnetism does affect the growth of plants and it made the plants on average one centimeter smaller in length when exposed to magnetism. It had been hypothesized that the plants with more magnets would make the plant grow the longest. The hypothesis was incorrect. In fact, the hypothesis was the opposite of what the results showed. The average growing length, for the Radish plants with no magnets was 5 (cm).The average growing length for Radish plants with 2 magnets was 4 (cm). The average growing length for the Radish plants with 4 magnets was 4 (cm). The average growing length for the Radish plants with 6 magnets was 5 (cm). The Radish plants with zero magnets in their presence grew the longest.
There was a strong relationship between the two variables. The plants with zero magnets had the most growth substantially, they were typically about twenty percent longer than the plants with exposure to the magnets. The trials showed that there was a relationship between the two variables, and that they often changed and made a large difference.
The results showed in the data, because it is believed that the plants were being pulled down by the magnetic fields in their presence. It showed that the magnets on average did not help the growth of the plant, but even more “stunted” the growth resulting in the plants being smaller in length. Research was done to find previous experiments involving radish plants and magnets, and the results were the complete opposite of this experiment. The other subjects conducting the experiments claimed that the plants grew substantially longer and substantially sturdier. All of the other experiments, except for this one showed data that stated that the plants were larger and more healthier in the presence of magnets. The results could be explained by the fact that the plants were only growing for one month, when the suggested growing time is over one month.
Some of the problems that arose during the experiment were that the plants did not all get equal amounts of sunlight which was difficult to control. Although they were mostly small things, they were difficult to control and virtually impossible, such as the one stated above. For the most part all of the variables and possible problems were avoided. No problems arose from the design. Some small things changed during the experiment such as giving the plants two cups of water everyday, which was changed during the process, to a sufficient amount. Things that could have been done differently were that the plants with the magnets were all in one large potting tray, which meant that some of the Radishes with only two magnets were getting more like four magnets worth of magnetic force, and vice-versa. If If the experiment were recreated, plants would be started a lot earlier than had been done so they would have more like two months or three months to grow opposed to one month. Late planting was somewhat of a downfall to the experiment.
There was no specialized technology needed for this experiment other than the magnets. The magnets were typical and are easily accessible from any store for home improvement. The knowledge gained through this experiment could be used for people that are growing plants.They could use it to know which plants to expose to magnetism while growing to have a positive impact on their growing, not a negative growing aspect as found in this experiment. The results could change the whole food industry. The results could change it by being able to produce plant species that are edible in a quicker and cleaner environment from the use of magnets. The results of my experiment could be used in most plant growing facilitates, they could plant magnets beneath the soil then grow the specific plant species, and have quicker, and more abundant sources of fruits and vegetables.
New questions could be, do the magnets affect growth of fruits? I feel that actual scientists should study this theory, to see whether the magnets actually have a significantly positive effect on the growth of certain plant species. I feel it would be really interesting to know that something you once studied turned into something, that they now use in most plant and fruit growing facilities.

Background Research


  • "Magneto-hydro-dynamics---or MHD---uses high ultrasonic frequencies and fluid dynamics to create an ion exchange. This magnetic water treatment lowers the surface tension of water and increases solubility and absorption of dissolved minerals and nutrients in the soil. Electromotive forces stimulate the roots and cause increased root growth and vigor."

In the Field

"Attach a strong magnet to the sprinkler or outlet of a garden hose. The north-pointing pole can aid in growth. The south-pointing pole can deter diseases. Magnetized water can break up compact soil to allow roots to grow and absorb minerals."

  • "MHD boosts fertilizer efficiency, increases the soil's moisture retention, conserves water and stimulates root development. Economic benefits include reduced waste of water and fertilizers."

A study was conducted to test the hypothesis that a magnetic field can affect plant growth and health. The study divided plants into three groups. The first group of plant seeds grew in a low magnetic field. The second group grew in a high magnetic field. The third group grew in the absence of a magnetic field, serving as a control group. Several growth parameters were measured, including the germination rate, plant height, and leaf size. In addition, the health status was measured by leaf color, spots, the stem curvature, and the death rate. Plant growth was observed continuously for four weeks. The results showed that magnetism had a significant positive effect on plant growth. Plant seeds under the influence of the magnetic field had a higher germination rate, and these plants grew taller, larger, and healthier than those in the control group. No adverse effects of magnetism on plant growth were noticed. However, the removal of the magnetic field weakened the plant stem, suggesting the role of magnetism in supplying plants with energy."

SFP Abstract
An experiment was conducted to test how magnetism affects the growth of Radish plants. It was hypothesized that Radishes exposed to six magnets would grow the tallest. Magnets were placed under the soil below the radish plants. The average length for the plants with 0 magnets was 5 cm. The average length for the plants with 2 magnets was 4 cm. The average length for the plants with 4 magnets was 5 cm. The average length for the plants with 6 magnets was 4.5 cm. The answer to the experiment was that radish plants exposed to magnetism grew less tall.
