Answer to Question #9294 in Electromagnetism for Nick Phillips
A long solenoid has a diameter of 12.0 cm. When a current i exists in its windings, a uniform magnetic field = 37.0 mT is produced in its interior. By decreasing i, the field is caused to decrease at the rate of 6.50 mT/s. Calculate the magnitude of the induced electric field at 8.2 cm?
