DERIVATION OF TORQUE EXPERIENCED BY A CIRCULAR LOOP IN UNIFORM MAGNETIC FIELD?
Asked by ARUN S | 03 Mar, 2015, 04:06: PM
answered-by-expert Expert Answer
The current carrying circular loop in uniform magnetic field behaves as a magnetic moment begin mathsize 12px style straight M with rightwards arrow on top end style acting perpendicular to its palne.
The torque acting on the circular current loop of magnetic moment M in the direction of magnetic field begin mathsize 12px style straight B with rightwards arrow on top end style
Torque, begin mathsize 12px style straight tau with rightwards arrow on top space equals space left parenthesis straight M with rightwards arrow on top space cross times space straight B with rightwards arrow on top right parenthesis end style
begin mathsize 12px style straight tau space equals space MBsinθ end style (θ is the angle between begin mathsize 12px style straight M with rightwards arrow on top space and space straight B with rightwards arrow on top end style)
