A square rectangular loop with sides of length 40 cm carries a
current of 3A and is located in a region of space in which there is
a uniform 𝐵 magnetic field of
module 0.5 T and whose direction forms an angle of 30º with the
plane of the loop. Calculate:
a) Magnetic dipole moment of the loop
b) moment of force on the loop
c) verify that this moment is worth
solution: a)𝑚 = 0.48 Am2, perpendicular to the plane of the
loop, clockwise b) 0.12 Nm
