MAGNETS

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 and steel.

Front

What are the two types of magnets?

Back

The two types of magnets are permanent magnets, which maintain their magnetic properties, and temporary magnets, which only exhibit magnetism when in a magnetic field.

Front

What is the magnetic field?

Back

The magnetic field is the region around a magnet where magnetic forces can be detected. It is represented by magnetic field lines that show the direction and strength of the magnetic force.

Front

What happens when a magnet is cut in half?

Back

When a magnet is cut in half, each half becomes a new magnet with its own north and south poles.

Front

What is the difference between magnetic attraction and repulsion?

Back

Magnetic attraction occurs when opposite poles (north and south) of magnets come together, while repulsion occurs when like poles (north-north or south-south) are brought together.

Front

What materials are attracted to magnets?

Back

Materials that are attracted to magnets include ferromagnetic materials such as iron, nickel, and cobalt.

Front

What is the north pole of a magnet?

Back

The north pole of a magnet is the end that points towards the Earth's geographic North when freely suspended.

Front

What is the south pole of a magnet?

Back

The south pole of a magnet is the end that points towards the Earth's geographic South when freely suspended.

Front

What is an electromagnet?

Back

An electromagnet is a type of magnet that is created by electric current flowing through a coil of wire, which generates a magnetic field.

Front

How can the strength of an electromagnet be increased?

Back

The strength of an electromagnet can be increased by increasing the current, adding more coils of wire, or using a ferromagnetic core.
