Magnetic Fields Review

Front

What is a magnetic field?

Back

A magnetic field is a region around a magnet where magnetic forces can be detected. It is represented by field lines that show the direction and strength of the magnetic force.

What happens to potential energy when two magnets are brought close together?

Back

The potential energy can either increase or decrease depending on the direction of the magnetic force and the movement of the magnets.

Front

What is kinetic energy?

Back

Kinetic energy is the energy of an object in motion. It depends on the mass of the object and its velocity.

Front

What is potential energy?

Back

Potential energy is the stored energy in an object due to its position or state. In the case of magnets, it is related to their position relative to each other.

Front

What occurs when like poles of magnets are brought together?

Back

Like poles (north-north or south-south) repel each other.

Front

What occurs when opposite poles of magnets are brought together?

Back

Opposite poles (north-south) attract each other.

Front

How is energy transferred when magnets move?

Back

Energy is transferred from potential energy to kinetic energy when magnets move due to magnetic forces.

Front

What is the relationship between potential energy and the position of magnets?

Back

The potential energy of magnets increases when they are moved against the magnetic force and decreases when they move in the same direction as the force.

Front

What happens to kinetic energy when magnets are released from a distance?

Back

When magnets are released, their potential energy converts to kinetic energy as they move towards each other.

Front

What is the effect of distance on the strength of a magnetic field?

Back

The strength of a magnetic field decreases as the distance from the magnet increases.
