Station 3: Simple Electric Motors:
1. Could you get any of the motors to keep spinning on its own? Describe your results.
2. This Simple Electric Motor works because electricity flows through the coil of wire, and a magnetic field is formed. The magnetic
field only forms when the bare wire touches the supports and current is flowing. The coil pushes away from the ceramic magnet
with enough force to turn it all the way around. As the coil turns around again, it becomes charged again and gets another push.
The process happens again and again to keep the coil spinning.
3. Would the motor spin if there was no magnet?
4. Would the motor spin if there was no current flowing through the wire?
5. When you are done, put everything back in the bin & flip your paper to green.
Station 4: Levitating Magnets:
1. How must the magnets be arranged in order to 'levitate' like they are?
2. When you are done, put the colored magnets back like they were at the beginning-so they are sticking together
and not levitating. Put everything back in the bin and flip your paper to green.
Station 5: Magnetic Putty:
1. Watch the magnet as ONE of you takes out their phone or laptop and looks up neodymium. What is neodymium?
2. The magnet you used in this experiment is made of neodymium.
3. Could you actually see the magnet move into the putty?
4. How far into the putty did the magnet get before you ran out of time?
