1. Electric Current Electric Circuit Electrons are pushed from atom to atom A series circuit with only one path for current to flow through. Electrons have negative charge Parallel circuits have an advantage over series circuit. The second bulb will still glow after the first bulb goes out.

2. Magnetic Fields Space around a magnet in which it can affect other magnets. Magnetic domain Is made up of a large number of atoms whose magnetic fields point in the same direction. Earth acts like a giant magnet. It has a magnetic field this is what causes all compasses to point north.

3. Electric Motor Is made of an electromagnet, a permanent magnet, and an object that changes the direction of the electric current. An electric motor changes electrical energy to kinetic energy.

4. Magnetism and Electricity Magnetic fields can also be used to make electric current in a wire. Generator Changes mechanical energy into electrical energy. They are made of a permanent magnet and a coil of wire. The coil must spin in order to produce an electric current
