Magnetic Forces

Front

What is a magnetic force?

Back

A magnetic force is the attraction or repulsion that arises between electrically charged particles due to their motion. It is one of the four fundamental forces of nature.

Front

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.

Front

What happens when like poles of magnets are brought together?

Back

Like poles (north-north or south-south) repel each other.

Front

What happens when opposite poles of magnets are brought together?

Back

Opposite poles (north-south) attract each other.

Front

What are magnetic field lines?

Back

Magnetic field lines are imaginary lines that represent the direction and strength of a magnetic field. They emerge from the north pole and enter the south pole.

Front

How does distance affect magnetic force?

Back

As the distance between two magnets increases, the magnetic force between them decreases.

Front

What is the strongest magnetic force?

Back

The strongest magnetic force occurs when magnets are closest to each other and aligned with opposite poles facing.

Front

What is an example of magnetic attraction?

Back

An example of magnetic attraction is when a refrigerator magnet sticks to the metal surface of the fridge.

Front

What is an example of magnetic repulsion?

Back

An example of magnetic repulsion is when two north poles of magnets are pushed together and do not touch.

Front

What is a magnetic field?

Back

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