Question

A circular wire loop with radius R carries a current i as shown. a) Draw the magnetic field inside and outside the loop. b) Use the Biot-Savart law to calculate the magnetic field magnitude at the precise center of the circle. (Hint: start by simplifying the cross product, and then add up the field due to little pieces ds of the wire.)
