... Recall that we first used Coulomb’s Law to calculate the electric force. Then we used F = qE and found the value of E by using Gauss’ Law. As we saw in the last chapter with F = qvB, if the magnetic field is known then we can easily calculate the magnetic force. Ampere’s Law helps us to find the mag ...
