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 magnetic field lines that show the direction and strength of the magnetic force.

Front

What happens when two like poles of magnets are brought close together?

Back

The like poles (north-north or south-south) repel each other.

Front

What happens when two opposite poles of magnets are brought close together?

Back

The opposite poles (north-south) attract each other.

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 the magnets relative to each other. It increases when magnets are moved apart against the magnetic force.

Front

What is kinetic energy?

Back

Kinetic energy is the energy of an object in motion. It increases as the speed of the object increases.

Front

How does the movement of magnets affect potential and kinetic energy?

Back

When magnets move closer together, potential energy decreases and kinetic energy increases as they accelerate towards each other.

Front

What is the relationship between speed and kinetic energy?

Back

Kinetic energy increases as speed increases, following the formula KE = 1/2 mv², where m is mass and v is velocity.

Front

What is the effect of moving a magnet against the magnetic force?

Back

Moving a magnet against the magnetic force increases the potential energy of the system.

Front

What is the significance of magnetic field lines?

Back

Magnetic field lines visually represent the strength and direction of a magnetic field, with closer lines indicating a stronger field.

Front

What happens to the energy in a system when two magnets attract?

Back

As two magnets attract, potential energy is converted into kinetic energy, causing them to move towards each other.
