Electricity and Magnetism By: Ally Arnold

Insulators An insulator is a material that resist the flow of electricity or heat. Ex. Plastic, dry wood, rubber, air.

Conductors A conductor is a material that can carry electricity or heat. Ex. Metal, gold, water, copper.

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
