Introduction
So far, we have discussed more than once about the interaction between electric current and magnetic field. Such an interaction produces a number of physical quantities such as magnetic force, torque, motor effect (motion), magnetic moment, dipole moment, work, energy and so on.
There are many other quantities and relationships we can find using the similarities between magnetic and electric properties of matter. One of them is Ampere's Law (named after the French physicist André-Marie Ampère), which is a mathematical statement of the relationship between currents and the magnetic fields they generate. It is thus the magnetic equivalent of Gauss's law, which relates charges to their electric fields. In this tutorial, we will discuss extensively about such a relationship, providing some mathematical background required to understand better the material discussed.
