Unformatted text preview: g V tsl191 – p.2/3 Magnetic Force Application (7) The rectangular 20-turn loop of wire is 10cm high and 5cm wide. It carries a current I = 0 . 1 A and is hinged along one long side. It is mounted with its plane at an angle of 30 ◦ to the direction of a uniform magnetic field of magnitude B = 0 . 50 T. • Calculate the magnetic moment μ of the loop. • Calculate the torque τ acting on the loop about the hinge line. 30 o a = 10cm I B b = 5cm tsl202 – p.3/3...
