What is an electromagnet?

• The flow of charges along a path

• A device that makes an electric current by converting kinetic energy to electric energy

• A device that changes electrical energy into mechanical energy

• A device in which electric current is used to produce magnetism

What is potential energy?

• Energy that an object has because of its position or its condition

• The energy an object has due to its motion

• Energy that is stored in matter and that can be released by a chemical reaction

• Energy caused by the movement of electric charges
