Magnetic Fields Review Flashcard #1

Front

What happens to the potential energy when a magnetic object moves away from a magnet?

Back

The potential energy increases because the object moves against the magnetic force.

Front

What do magnetic field lines indicate about the interaction between two magnets?

Back

Magnetic field lines show the direction of the magnetic force; like poles repel and opposite poles attract.

Front

What is the relationship between potential energy and kinetic energy in a system of magnets?

Back

Some potential energy changes into kinetic energy when magnets move due to magnetic force.

Front

How does magnetic force affect energy when magnets are released?

Back

The magnetic force changes potential energy into kinetic energy.

Front

What is potential energy in the context of magnets?

Back

Potential energy is the stored energy in a system due to the position of magnets relative to each other.

Front

What is kinetic energy in the context of magnets?

Back

Kinetic energy is the energy of motion that magnets have when they move.

Front

What happens to the energy in a system of magnets when they attract each other?

Back

Some potential energy is converted into kinetic energy as they move towards each other.

Front

What is the effect of distance on the potential energy between two magnets?

Back

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

Front

What is the significance of identical magnetic carts in a magnetic field experiment?

Back

Identical carts help isolate the effect of magnetic forces on potential and kinetic energy changes.

Front

What is the principle of conservation of energy in a magnetic system?

Back

Energy in a magnetic system is conserved; it can change forms but the total energy remains constant.
