50. Two Coils [2P+2P+2P] A current I? goes through a cylindrical coil (1) with length and number of turns N?. Inside of that coil there is another coil (2) with number of turns N? and a turn area A? (Figure 1). Inside the coils is air. 1 = 50 cm, N? = 250, N? = 40, A2 = 20 cm², Io = 5 A, f = 40s-¹, R? = 0.29, T = 8.2 ms a) Determine the induced voltage in coil (2) and calculate the mutual inductance M (Uind -M) for the given values. b) Due to a capacitor discharge a current of I?(t) = Inexp(-t/r) goes through coil (1). What is the induced voltage in coil (2) over time? What is the initial induced voltage at t=0? c) Coil (2) now starts to rotate around the axis S with a frequency f. For the given values, calculate the maximum induced current in coil (2) if the current that goes through coil (1) is constant (I(t)= Io). The total resistance of circuit (2) is R?.
