A current I is flowing through the loop. The direction of the current and the shape of the loop are as shown in the figure. The magnetic field at the centre of the loop is (mu_(0)I)/(R ) (MA=R,MB=2R,angleDMA=90^(@))

A current I is flowing thorugh the loop. The direction of the current and the shpae of the loop are as the shown in the figure. The magnetic fild at the centre of the loop is (mu_(0) I)/(R) times (MA = R, MB = 2R, /_DMA = 90^(@))
