Explain how to make an electromagnet
You need a nail, wire and a battery. Wrap the wire around the nail creating many coils. Connect each end of battery at the positive and negative terminals with wire.
What are some energy sources that generators produce electricity?
1. Steam
2. Flowing water
3. Wind

Things that make electromagnet stronger
What is...
1. More coils tighter
2. Stronger battery
3. Longer piece of Iron

This object works by opening and closing a circuit. When object is on the circuit is closed and electricity can run through it. When object os off circuit is open and electricity cannot flow because the object has created a gap in the circuit.
