Problem 7: A circular coil is made up of N= 380 closely wrapped tumns of wire and has a adius R = 0.15 m. A counterclockwise current I= 2.9 A is in the coil. The coil is situated in a B nagnetic field of magnitude B = 1.4 T. The magnetic field points to right. I Part (a) Express the magnetic dipole moment u in terms of the number of the turms N, the current I, and radius R. Part (b) Calculate the numerical value of u in SI units. Part (d) Express the magnitude of the torque r in terms of u and B. =1
