- O Resources Give Up O Hint A 145 turn circular coil of radius 2.29 cm is immersed in a uniform magnetic field that is perpendicular to the plane of the coil. Over an interval of 0.169 s, the magnetic field strength increases from 55.7 mT to 99.3 mT. Find the magnitude of the average emf Eve induced in the coil during this time interval, in millivolts. Eve = mVThe current in a long solenoid of radius 6 cm and 22 turns/cm is varied with time at a rate of 3 A/s. A circular loop of wire of radius 8 cm and resistance 7 0 surrounds the solenoid. Find the electrical current induced in the loop (in HA). HAAn emf of 18.0 mV is induced in a 525-turn coil when the current is changing at the rate of 10.0 A/s.
