Magnetic moment, M=I×A...........(1) where I is current and A is area
I=eT=e2πrv=ev2πr
A=πr2
Angular Momentum J=mvr.......(2)
Put values of I and A in equation (1)
M=ev2πrπr2
M=evr2
M=eJ2m(∵vr=Jm)
E,m,J and G denote energy, mass, angular momentum and gravitational constant respectively. Then the dimensions of EJ2m5G2 are
