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.

    After surfing the "entire" internet to solve & grasp this Griffiths example 5.6 edition 4th. I finally found peace here. Now I can rest my mind and go forward. the hardest part it was at 12: 40 & 14:46 to figure out first the horizontal components cancel out and then the cos𝛼 that I couldn't picture out. It is simple but you need to see it through. This is so beautiful when Maths & Physics makes sense.
