What happens to the poles of a magnet when you break a magnet in two pieces.
What is the two magnets will each have a north and south pole.
200
The three ways to make an electromagnet stronger.

400
What would happen if one bulb burns out in a parallel circuit string of Christmas lights.
What is the electricity would still flow to the working bulbs in a parallel circuit.
400
Created by a solar flare that reaches the Earth.
What is the Northern Lights or Aurora Borealis.
400
How a doorbell turns electrical energy into mechanical energy.
What is the electrical energy powers an electromagnet that creates a magnetic field which attracts and repels a metal arm that rings the bell.
400
Types of mechanical energy that can spin a generator.
What is wind power, hydroelectric power, nuclear power, or steam power.
500
Caused by an imbalance between positive and negative charges.
What is static electricity.

What happens to a light bulb when a larger power source is added.
What is the bulb will give off more light and more thermal energy.
500
The reason that the Earth has a magnetic field unlike other planets in our solar system.
What is the Earth is a giant electromagnet because it has a solid iron core surrounded by a rotating liquid core that carries an electric current which generates a magnetic field.
500
The reason that electric motors need electromagnets.
What is electric motors need electromagnets to turn electrical energy into mechanical energy.
500
How a flashlight can work without batteries.
What is the flashlight has a small generator inside that produces electrical energy from shaking it or turning a crank.
