A 38.8 turns circular coil with radius 7.84 cm and resistance 7.72ohms is placed in a magnetic field directed perpendicular to theplane of the coil. The magnitude of the magnetic field varies intime according to the expression B = a1 * t + a2*t2 , where a1 =0.0483 T/s, a2 = 0.0558 T/s2 are constants, time t is in secondsand field B is in Tesla. Find the magnitude of the induced emf inthe coil at t = 1.37 s. Answer in units of V.
--------------- part 2 is problematic
An AC generator consists of eight turns of wire, each of area0.0722 m^2, and total resistance of 12ohms. The loop rotates in theexternal magnetic field of strength 0.76 T at a constant frequencyof 48.1 Hz. What is the maximum induced emf?
Answer in units of V.
