Electro-magnets and motors

Q1. a motor converts electrical current into:

• chemical energy

• electric energy

• mechanical life

• mechanical energy/force

electric current can cause a magnetic field

• True

• False

electric generators converts mechanical force/energy into

• mechanical energy

• magmatism

• electric energy

• chemical energy

What can you use to make an electromagnet?

• Battery, nail and string

• Battery, pencil and wire

• Wire, battery and nail

• Peanut butter, lampshade, hand sanitizer

What is the transfer of energy in when you plug in a motor and it spins?

• chemical to mechanical

• electrical to mechanical

• mechanical to electrical

• physical to potential

How are electromagnets different from magnets?

• magnets can be turned on/off

• you can turn an electromagnet on/off

• magnets are more powerful

• magnets have a North and South pole

If I were to try to connect the north pole of one magnet to the north pole of another magnet, the two poles would:

• repel

• attract

• neither

• flip
