MAGNETISM & ELECTRICITY

Magnetism The attraction of one magnet to another

Magnetic Pole The area around the magnet where the magnetic effect is strongest Like poles repel South ,South North ,North Unlike poles attract South ,North

Magnetic Field The region of magnetic force around a magnet. this allows magnets to interact without touching

Iron bearing metals Materials that shows strong magnetic effects Iron Nickel cobalt

What is Static Electricity ? The build up of charge on an object These charges do not flow Rubbing certain materials together is a build up of static electricity. Lightning is static electricity.

Benjamin Franklin Discovered lightning was an electric current and built the first lightning rod.

Electric Current Current: flow of electrons through a material

Circuits A pathway taken by an electric current. Closed circuits: allow the movement of electrical energy Open circuits: stop the movement of electrical energy.

Circuits Series Circuit: only one path for current to flow through Parallel Circuit: more than one path for current to flow through

How does electricity move? Conductors: allow electricity to move through them (metals) Insulators: do not allow electricity to move through them (rubber, plastic, wood)

Electromagnet Current flowing through a wired that’s been wrapped around an iron-bearing metal. This is a temporary magnet.

Michael Faraday Discovered that an electric motor could be made using electricity and magnetism.
