Explanation / Answer

magnetic moment = I*A

A = areal vector

curl the right hand fingers in the direction of current ,

thumb gives the direction of area vector

here the thumb points right

The right side of the bar

======================================

maximum torque = N*I*A*B

maximum torque = 50*4*0.06^2*B = 0.72*B

B is missing the image

substitue the value of B and get the answer

------------------------

48)

magnetic field B = uo*I//(2*pi*r)

B = 4*pi*10^-7*2/(2*pi*0.1)

B = 4*10^-6 T <<<<-----------ANSWER
