Magnetic Fields Review Flashcard #1

Front

What is potential energy in the context of magnetic fields?

Back

Potential energy is the energy stored in an object due to its position in a magnetic field. It increases when an object is moved against the magnetic force.

Front

How does moving a magnet toward another magnet affect potential energy?

Back

Moving a magnet toward another magnet that cannot move increases the potential energy of the system because it is moving against the magnetic force.

Front

What happens to two magnetic objects that are close to each other?

Back

They will experience a magnetic force that can either attract or repel them, depending on their polarities.

Front

What is the effect of distance on potential energy in a magnetic field?

Back

The potential energy increases as the distance between two magnets decreases when they are moving against the magnetic force.

Front

What is the difference between attraction and repulsion in magnets?

Back

Attraction occurs when opposite poles of magnets come close, while repulsion occurs when like poles are near each other.

Front

What is the role of a fixed magnet in a magnetic system?

Back

A fixed magnet provides a constant magnetic field that affects the potential energy of other movable magnets in the system.

Front

How does the movement of a magnetic cart affect its potential energy?

Back

Moving a magnetic cart closer to a fixed magnet increases its potential energy, while moving it away decreases its potential energy.

Front

What is the significance of identical magnetic objects in experiments?

Back

Identical magnetic objects ensure that any changes in potential energy are due to their positions relative to the magnetic field, not differences in their properties.

Front

What is a magnetic force?

Back

A magnetic force is the attraction or repulsion between magnetic objects, which can cause them to move toward or away from each other.

Front

What happens when two magnets are brought together?

Back

They will either attract or repel each other based on their polarities, affecting their potential energy.
