Electricity and Magnetism By: Ally Arnold
3
Insulators An insulator is a material that resist the flow of electricity or heat. Ex. Plastic, dry wood, rubber, air.
4
Conductors A conductor is a material that can carry electricity or heat. Ex. Metal, gold, water, copper.
5
Static Electricity Before Static electricity is caused by friction. During During an electric shock, charges exchange After The two objects are electrically neutral. Lightning is a form of static electricity.

Circuits Series This circuit has multiple light bulbs. Open: it can’t work because one bulb is missing and can’t make a full circle. Closed: it can work because it can make a full circle. Main Parts power source conductor light bulb Simple This circuit has one light bulb. Open: it can not work because it can’t make a full circle. Closed: it can work because it can make a full circle. Parallel This circuit has multiple light bulbs and has one conductor for each bulb. Open: it can work because it can make a full circle and still have a bulb missing. Closed: it can work because it can make a full circle.

Magnets Similarities Both bar magnets and electromagnets attract iron. Both are a type of magnet. Both have magnetic fields. Electromagnet Differences An electromagnet uses a power source a bar magnet does not. A bar magnet has two poles an electromagnet does not have any. A bar magnet is permanent an electromagnet is temporary. Bar magnet
