Magnetism

Front

What happens to the force between two magnets as the distance between them increases?

Back

The force decreases.

Front

What are the lines that represent the magnetic field around a magnet called?

Back

Magnetic field lines.

Front

How does a permanent magnet differ from a temporary magnet?

Back

A permanent magnet keeps its magnetism for a long time.

Front

What type of materials are Iron, Nickel, and Cobalt classified as?

Back

Ferromagnetic materials.

Front

Which material would be attracted to the north end of a magnet?

Back

Paper clips.

Front

What is the definition of magnetism?

Back

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

Front

What is a magnetic field?

Back

A magnetic field is the region around a magnet where magnetic forces can be detected.

Front

What is the role of magnetic domains in ferromagnetic materials?

Back

Magnetic domains are regions within ferromagnetic materials where the magnetic moments of atoms are aligned in the same direction.

Front

What is the effect of temperature on the magnetism of ferromagnetic materials?

Back

Increasing temperature can cause ferromagnetic materials to lose their magnetism, a phenomenon known as thermal demagnetization.

Front

What is the right-hand rule in magnetism?

Back

The right-hand rule is a mnemonic for understanding the direction of magnetic fields and forces; if you point your thumb in the direction of current flow, your fingers curl in the direction of the magnetic field.
