What is magnetic fields?

The magnetic field is the area around a magnet in which the effect of magnetism is felt. The magnetic field is used to describe how the magnetic force is distributed in the space around and within something magnetic in nature.

A moving charge in a magnetic field experiences a force perpendicular to its own velocity and to the magnetic field.

The properties of magnetic field are

• The direction of the magnetic field lines is from the south pole to the north pole.
• Magnetic field lines never intersect with each other.
• Magnetic field lines form a closed-loop.
• Field lines have both direction and magnitude at any point on the field.
