Data Analysis
3 battery picked up more paper clips then 1 batty 2 and 3 picked the most paper clips.

Conclusion
No, it did not turn out the way I want it because I thought it would turn out that the fourth battery would work. I might not have put the wire right so it could have just malfunctioned. I would have wired it right, so next time it would work.
