MAGNETS

Front

What materials are attracted to magnets?

Back

Magnets attract ferromagnetic materials such as iron and steel.

Front

What is an electromagnet?

Back

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

Front

How can you increase the strength of an electromagnet?

Back

You can increase the strength of an electromagnet by increasing the amount of current flowing through the wire.

Front

What happens when you move a magnet near a coil of wire?

Back

Moving a magnet near a coil of wire induces an electric current in the wire.

Front

What is magnetism?

Back

Magnetism is a non-contact force that can attract or repel certain materials.

Front

What are magnetic objects?

Back

Magnetic objects are materials that are attracted to magnets, such as iron, nickel, and cobalt.

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 the presence of a magnetic field.

Front

What is a magnetic field?

Back

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

Front

What is the role of a core in an electromagnet?

Back

A core, often made of iron, enhances the magnetic field produced by the electromagnet.

Front

What is the right-hand rule in electromagnetism?

Back

The right-hand rule is a method to determine the direction of the magnetic field around a current-carrying wire.
