The magnetic flux through a coil of wire containing 4 limps changes from -50Wb to +42Wb in 0.6 s. What is the induced emf in the coil? The coil of wire has an area of 4 times 10^-4m. The wire is now placed in a uniform magnetic field B = 2.5 times 10^-2 T. The current flowing in the loop is 1.5A. Calculate the magnetic moment mu and Find the maximum torque.

During a transcranial magnetic stimulation (TMS) treatment, a magnetic field, typically of magnitude 5.00 T, is produced in the brain using external coils. During the treatment, the current in the coils (and hence the magnetic field in the brain) rises from zero to its peak in about 75.0 us . Assume that the magnetic field is uniform over a circular area of diameter inside the brain. What is the magnitude of the average induced emf around this region of the...
