Magnetic Fields Quiz

Magnetic field lines are imaginary lines that provide an alternative way to represent the information contained within a magnetic vector field. The density of the lines indicates the magnitude of the field. The magnetic field is stronger and crowded near the poles of a magnet, while it becomes weaker and the lines become less dense as we move away from the poles.

The magnetic field can be mathematically described as a vector field, which is a set of many vectors drawn on a grid. Each vector points in the direction that a compass would point and has a length dependent on the strength of the magnetic force.

Magnetic field intensity, also known as magnetic intensity, is represented as vector $H$ and is defined as the ratio of the MMF needed to create a certain Flux Density ($B$) within a particular material per unit length of that material.
