A physics experiment with magnets and a vote pole-results
This is an experiment with magnets in motion.
The question is that if one magnet is spinning along a circular plane such that
the north end arrives at a point on the circle just as often as the south end, then what will happen if another magnet is brought close to the spinning one and held with the south end facing and parrellel to the plane? Will the spinning magnet attract to the stationary one or repel or do nothing?
What if the north end of the stationary one is brought close to the spinning magnet?
What would you guess will happen?
Requires:
Safety glasses!(magnets chip easily and anything moving at high speed is dangerous, except watermellons),
one small electric motor and a battery,
2 magnets or several magnets clustered together, a length of fishing string and some tape.
approximate cost $8 at radioshack
Putting it together:
Using the tape to anchor the electric motor to a desk, and taping up a cluster of magnets to lessen chipping in case they contact, attach one end of the
fishing string to the magnet at the middle so that as it spins the charged ends are moving around not rotating up and down, and attach the other end to the shaft of the motor( one may need to file a tiny grove around the shaft to get keep the string from slipping off or super glue it on).
Also a 1.5V battery and a thumb sized motor is plenty to get the magnet up to a high rate of spin.
