A 52.5-turn circular coil of radius 5.10 cm can be oriented in any direction in a uniform magnetic field having a magnitude of 0.525 T. If the coil carries a current of 23.3 mA, find the magnitude of the maximum possible torque exerted on the coil. N · m A rectangular coil consists of N = 120 closely wrapped turns and has dimensions a = 0.400 m and b = 0.300 m. The coil is hinged along the y axis, and its plane makes an angle theta = 30.0 degree with the x axis (see figure below). What is the magnitude of the torque exerted on the coil by a uniform magnetic field B = 0.500 T directed in the positive x direction when the current is I = 1.20 A in the direction shown? N · m If you are looking downward from the positive y direction, what is the expected direction of rotation of the coil? clockwise counterclockwise

Explanation / Answer

torque= NIAB sin theta

so answer = 4.32 N.M
