Uniform magnetic field on a circular coil? Best answer, 5 Stars for CORRECT answer.?



A wire of length 19.0 cm carrying a current of 4.38 mA is to be formed into a circular coil and placed in a uniform magnetic field B(vector) of magnitude 5.57 mT. The torque on the coil from the field is maximized.

(a) What is the angle between B(vector) and the coil's magnetic dipole moment?

(b) What is the number of turns in the coil?

(c) What is the magnitude of that maximum torque?
