Mod 3: Electromagnetic Forces (L1, L2, L3)

Front

What happens when an object made of magnetic material comes in contact with a magnet?

Back

Its magnetic domains fall into alignment and it begins to attract other objects made of magnetic material.

Front

What type of charges will experience an electric force of attraction?

Back

Opposite charges.

Front

What does a compass needle act as?

Back

A magnet.

Front

True or False: The magnetic domains of a permanent magnet are arranged randomly.

Back

False.

Front

True or False: An object is electrically neutral when the amount of positive charge equals the amount of negative charge.

Back

True.

Front

What are magnetic domains?

Back

Regions within a magnetic material where the magnetic fields of atoms are aligned in the same direction.

Front

What is the definition of a magnet?

Back

An object that produces a magnetic field and can attract or repel other magnetic materials.

Front

What is the difference between permanent magnets and temporary magnets?

Back

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

Front

What is an example of a magnetic material?

Back

Iron.

Front

What is the principle behind how a compass works?

Back

A compass works by aligning its needle with the Earth's magnetic field.
