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

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 the direction of magnetic field lines?

Back

Magnetic field lines emerge from the north pole of a magnet and enter the south pole.

Front

What is the role of magnetic force in the movement of magnets?

Back

Magnetic force can either attract or repel magnets, causing them to move towards or away from each other.

Front

What is the significance of the strength of a magnetic field?

Back

The strength of a magnetic field determines how strong the magnetic force is; stronger fields can attract or repel objects more effectively.

Front

What is a magnetic pole?

Back

A magnetic pole is one of the two ends of a magnet where the magnetic force is strongest; every magnet has a north and a south pole.

Front

How can you visualize magnetic field lines?

Back

Magnetic field lines can be visualized using iron filings sprinkled around a magnet, which align along the lines of force.

Front

What is the difference between permanent magnets and temporary magnets?

Back

Permanent magnets maintain their magnetic properties over time, while temporary magnets only exhibit magnetism when in a magnetic field.

Front

What is the effect of distance on magnetic force?

Back

The magnetic force decreases as the distance between two magnets increases.
