Define Uniform and Non-uniform Magnetic Field

Uniform Magnetic Field: Magnetic field is said to be uniform if the magnetic induction has the same magnitude and the same direction at all the points in the region. It is represented by drawing parallel lines (Figure).

An example of the uniform magnetic field over a wide area is the Earth’s magnetic field.

Non-uniform Magnetic Field: If the magnetic induction varies in magnitude and direction at different points in a region, the magnetic field is said to be non-uniform. The magnetic field due to a bar magnet is non-uniform.

It is represented by convergent or divergent lines.
