Magnetism and Electromagnetism

Front

What are magnetic domains?

Back

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

Front

True or False: All metals are attracted to magnets.

Back

False. Only certain metals, like iron, nickel, and cobalt, are attracted to magnets.

What is an electromagnet?

Back

An electromagnet is a type of magnet in which the magnetic field is produced by an electric current.

Front

What materials are typically used to make a strong electromagnet?

Back

Iron is commonly used as a core material to enhance the magnetic field of an electromagnet.

Front

What is the difference between permanent magnets and electromagnets?

Back

Permanent magnets maintain a constant magnetic field, while electromagnets can be turned on and off by controlling the electric current.

Front

What is the role of electric current in electromagnetism?

Back

Electric current generates a magnetic field, which is the principle behind electromagnets.
