Expert Answer:

Consider a circular loop with a charge q moving in a circle of radius r and speed v having centre O. Let I be the current flowning through the circular loop. let dl be the lengh of element.

From the Biot- Savart's law, Magnetic field at the center of loop due to current I is given by,
