Magnets & Magnetic Force

Front

What is a magnet?

Back

A magnet is an object that produces a magnetic field, which can attract or repel certain materials, such as iron.

Front

What is a magnetic field?

Back

A magnetic field is the area around a magnet where magnetic forces can be detected and where magnetic materials experience attraction or repulsion.

Front

What materials are typically attracted to magnets?

Back

Materials like iron, nickel, and cobalt are typically attracted to magnets.

Front

What is the difference between a permanent magnet and a temporary magnet?

Back

A permanent magnet maintains its magnetic properties over time, while a temporary magnet only exhibits magnetism when in the presence of a magnetic field.

Front

What does it mean for a material to be magnetized?

Back

A material is magnetized when its magnetic domains are aligned in the same direction, allowing it to exhibit magnetic properties.

Front

What are magnetic domains?

Back

Magnetic domains are small regions within a material where the magnetic fields of atoms are aligned in the same direction.

Front

What happens to the magnetic domains in an unmagnetized material?

Back

In an unmagnetized material, the magnetic domains are randomly oriented, canceling each other out and resulting in no overall magnetism.

Front

What is the effect of distance on magnetic force?

Back

The strength of the magnetic force decreases with increasing distance from the magnet.

Front

Can magnets attract non-magnetic materials?

Back

No, magnets cannot attract non-magnetic materials like wood, plastic, or paper.

Front

What is an example of a temporary magnet?

Back

An example of a temporary magnet is a paperclip that becomes magnetized when in contact with a magnet.
