A flat 103turn currentcarrying loop is immersed in a uniform

A flat 103-turn current-carrying loop is immersed in a uniform magnetic field. The area of the loop is 5.47 cm2 and the angle between its magnetic dipole moment and the field is 41.9

Solution

magnetic momet=iA

so,

torque=nuXB

or 2.95*10^-5=niAB sin41.9

or 2.95*10^-5=103*2.33*10^-3*5.47*10^-4*B*0.6678

or B=0.3365 T
