Amplify Magnetism

What happens to the energy in a system of magnets when the magnetic force causes two magnets to move?

• The potential energy in the system increases.

• The kinetic energy in the system decreases.

• Some of the potential energy is converted to kinetic energy.

• Some of the kinetic energy changes to potential energy.

What is kinetic energy?

• The energy that is stored in an object or system

• To push objects away from each other

• The energy that an object has because it is moving

• To move from one object to another

What is potential energy?

• The energy that an object has because it is moving

• The energy that is stored in an object or system

• To provide evidence against a claim

• One of the two opposite ends of a magnet

What happens to the potential energy if you were to move magnet 2 toward magnet 1?

• The potential energy does not change because the magnets in the system do not change.

• The potential energy increases because Magnet 2 moves against the magnetic force.

• The potential energy decreases because Magnet 2 moves against the magnetic force.

• The potential energy decreases because Magnet 2 moves in the same direction as the magnetic force.

Based on the magnetic field lines diagram, what will happen next with these sets of magnets?

• In both sets the magnets will attract.

• In both sets the magnets will repel.

• In Set 1 the magnets will repel and in Set 2 the magnets will attract.

• In Set 1 the magnets will attract and in Set 2 the magnets will repel.

What will happen when these magnets are let go?

• The magnets will not move because they are not touching.

• The magnets will move closer to each other because the magnetic force will pull them together.

• The magnets will move away from each other because the magnets are not touching.

• The magnets will move away from each other because the magnet force will push them apart.
