Magnetism/Electromagnetism Review

Front

What is the function of a generator?

Back

A generator converts mechanical energy into electrical energy.

Front

What are the magnetic poles of a magnet?

Back

The ends of a magnet where the magnetic force is strongest; typically referred to as North and South poles.

Front

What does a transformer do?

Back

A transformer transforms voltage from one level to another.

Front

What is required for a material to be magnetic?

Back

A material must have areas of domains all aligned in the same direction.

Front

What happens when a bar magnet is broken in half?

Back

It creates two magnets, each with both a North and a South pole.

Front

What is magnetism?

Back

Magnetism is a physical phenomenon produced by the motion of electric charge, resulting in attractive and repulsive forces between objects.

Front

What is the difference between a permanent magnet and an electromagnet?

Back

A permanent magnet maintains its magnetic properties without external influence, while an electromagnet's magnetism is produced by an electric current.

Front

What is the right-hand rule in electromagnetism?

Back

The right-hand rule is a mnemonic for understanding the direction of magnetic fields and forces in relation to current flow.

Front

What is the role of magnetic field lines?

Back

Magnetic field lines represent the direction and strength of a magnetic field; they emerge from the North pole and enter the South pole.

Front

What is the relationship between electricity and magnetism?

Back

Electricity and magnetism are interrelated; a changing electric field produces a magnetic field and vice versa.
