What is the difference between uniform and non-uniform magnetic field lines?

Uniform magnetic lines as the name suggests are composed of lines that point to the same direction and of the same magnitude. This means all of these lines exert the same force. Non-uniform relates to different directions of the lines and a varied magnitude.
