Amplify Magnetic Fields Pre-Assessment

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

They repel each other.

Front

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

Back

They attract each other.

Front

What is potential energy in the context of magnets?

Back

Potential energy is the energy stored in an object due to its position in a magnetic field. The further away a magnetic object is from a magnet, the higher its potential energy.

Front

How does distance affect the strength of a magnetic force?

Back

The strength of a magnetic force decreases as the distance between the magnets increases.

Front

What is the role of magnetic field lines?

Back

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

Front

What is the significance of moving a magnetic object away from a magnet?

Back

Moving a magnetic object away from a magnet increases its potential energy because it is moving to a position of higher energy.

Front

What is the difference between magnetic attraction and repulsion?

Back

Magnetic attraction occurs between opposite poles (north and south), while magnetic repulsion occurs between like poles (north-north or south-south).

Front

What is a magnetic force?

Back

A magnetic force is the push or pull that magnets exert on each other or on magnetic materials.

Front

What is the effect of a stationary magnet on moving magnetic objects?

Back

A stationary magnet can exert a magnetic force on moving magnetic objects, causing them to accelerate towards or away from the magnet depending on their poles.
