Hi All,
My daughter did a science experiment on homopolar motors. The only variable was the number of magnets on each motor. We found out through the experiment that the more magnets we attached to the motor, the longer it spun before the battery died. I'm assuming it has to do with the magnetic force causing it to spin more efficiently. I've found all sorts of info on why the motor spins but nothing to explain our findings. Can anyone help or point us in the right direction? Thanks so much!
