What is a magnetic field?

Back

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

What are magnetic poles?

Back

Magnetic poles are the regions of a magnet where the magnetic force is strongest. Every magnet has a north pole and a south pole.

What happens when like magnetic poles are brought together?

Back

Like magnetic poles repel each other. For example, two north poles will push away from each other.

What happens when opposite magnetic poles are brought together?

Back

Opposite magnetic poles attract each other. For example, a north pole and a south pole will pull towards each other.

What is the direction of magnetic field lines?

Back

Magnetic field lines point from the north pole to the south pole of a magnet.

What is the relationship between electricity and magnetism?

Back

Electricity can create a magnetic field, and a changing magnetic field can induce an electric current. This relationship is known as electromagnetism.
