Changing the materials of the core will change the what of the electromagnet?
What is strength?
This is a material that does not allow electricity to pass through easily.
What is electric insulator?
This is a circuit that is not connected in some area, so electrons do not flow through. Electricity is off.
What is open circuit?
Electricity can be transferred to these forms

What is form to another?
Adding more batteries to the circuit will ______ the strength of the electromagnet.
What is increase?
These repel or move away from each other.
What are like poles?
This circuit is when there is only one path in which the energy can flow.
What is series circuit?
Electrical energy can be changed to light energy in these.
What are lamps, televisions, and computer monitors?
When I exercise, I use this.
What is energy?
This is a temporary magnet formed by passing an electric current through a wire coiled around an iron ore.
What is an electromagnet?
When an electrical current is running through the wire, the magnetic core produces this
What is a magnetic field?
This circuit is when there are two or more paths in which the energy can flow.
What is parallel circuits?
