Distinguish between Uniform magnetic field and Non- uniform magnetic field?

Explanation

(i) Uniform magnetic field : Magnetic field is said to be uniform if it has same magnitude and direction at all the points in a given region . Example, locally Earth's magnetic field is uniform .
(ii) Non- uniform magnetic field : Magnetic field is said to be non - uniform if the magnitude or direction or both varies at all its points . Example: magnetic dield of a bar magnet
