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

SeriesThis 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.
