FLASHCARD QUESTION

Front

What is potential energy in the context of magnetic fields?

Back

Potential energy is the energy stored in a system due to the position of magnets relative to each other. It increases when magnets are moved closer together against the magnetic force.

2.

FLASHCARD QUESTION

Front

What happens to potential energy when a magnet is moved away from another magnet?

Back

The potential energy decreases because the magnets are moving apart, which is in the direction of the magnetic force.

3.

FLASHCARD QUESTION

Front

What is the principle of magnetic attraction?

Back

Magnets attract when opposite poles (north and south) are brought close together, resulting in a decrease in potential energy.

4.

FLASHCARD QUESTION

Front

What is the principle of magnetic repulsion?

Back

Magnets repel when like poles (north-north or south-south) are brought close together, resulting in an increase in potential energy.

5.

FLASHCARD QUESTION

Front

How does the distance between two magnets affect their potential energy?

Back

As the distance between two magnets decreases, the potential energy increases, and as the distance increases, the potential energy decreases.

FLASHCARD QUESTION

Front

What is a magnetic field line diagram?

Back

A magnetic field line diagram visually represents the direction and strength of a magnetic field, showing how magnets will interact with each other.

7.

FLASHCARD QUESTION

Front

What is the significance of the direction of magnetic force?

Back

The direction of magnetic force determines whether magnets will attract or repel each other, influencing the potential energy in the system.
