Magnetic field on the axis of a circular loop | Moving charges & magnetism | Physics | Khan Academy

We start by using Biot-Savart's law to calculate the magnetic field due to a small current element of the circular loop. Then we integrate that expression over the entire loop to find the total magnetic field on the axis.
