Opposite poles attract. Like poles repel. Force is dependent on distance

What are the characteristics of magnets?

Magnetism?

Attraction of a magnet for another object.

What does magnetism have to do with electricity?

What is it creates a magnetic field?

When magnets are further apart, what happens to the magnetic field?

It grows weaker.

When magnets get closer together, what happens to the magnetic field?

It grows stronger.

Copper Aluminum Platinum Gold Silver Water People and Animals Trees.

What are conductors?

Glass Porcelain Plastic Rubber

What are insulators?

Why are humans a good conductor of electricity?

Electricity will always take the shortest path to the ground. Your body is 60% water and that makes you a good conductor of electricity. If a power line has fallen on a tree and you touch the tree you become the path or conductor to the ground and could get electrocuted.

Why do we use insulators on wires?

The rubber or plastic on an electrical cord provides an insulator for the wires. By covering the wires, the electricity cannot go through the rubber and is forced to follow the path on the aluminum or copper wires.

Energy comes from:

What is a power source?

In a circuit, why are the wires made of copper?

Copper is a conductor

Explain which circuit will have brighter light and why:

Circuit 1 will have brighter light because it has to transfer energy into 2 light bulbs and circuit 2 has to light 3 bulbs.

Explain the difference between a series circuit and a parallel circuit.

In a series circuit, the energy only has one way to travel. In a parallel circuit, the energy can go more than one way.

Explain what happens if one of the bulbs burn out.

The other bulb will be brighter because it will get all of the electricity.

Energy is transferred from a power source and then it can power a light bulb, a sound, and produce heat?

Why does a circuit work?

Margaret Mead

anthropologist, writer, scientist; environmentalist, women's rights advocate, studied tribes in India

Nikola Tesla

The "Tesla coil," Tesla also invented fluorescent lights and a new type of steam turbine, and he became increasingly intrigued with the wireless transmission of power.

Michael Faraday

British physicist and chemist, best known for his discoveries of electromagnetic induction and of the laws of electrolysis. His biggest breakthrough in electricity was his invention of the electric motor

Benjamin Franklin

Describe the graph below:

Temperature changes from day to night It is a line graph and shows change over time.

Using this table can you tell what happens to the electromagnet when you add more loops?

It gets stronger.
