Question

) An inductor is formed hy winding V tuns of a thin conducting wire into a circular f radius a. The inductor toop is in the plane with its center at the origin and connected to a resistor R. In the presence of a loop as shown below around a non-magnetic material r- y magnetio field B ธิ 2094 + Z)sin(at) wb/m.. Teslas. where ω-angular frequency Derive and calculate the following parameters (a) Derive the magnetic flux linking a single turn of the inductor (b) Calculate the transformer emf (ver), for N-20, a # 5cm, and f s| MHz. (c) What is the self-inductance L of this 20-turn inductor. (d) Draw an equivalent circuit showing the coil as a sinusoidal source, with two resistors. The resistance of the connected resistor is R = 10 Ω and the internal resistance of the coil is 5 0. Label the correct polarity of the Vthar when t T/4 where T 1/f is the period of the sinusoidal signal. (e) Calculate the induced current / and voltage drop Ve across the resistor R at time t T/4 Indicate on your schematic the direction of this current at this instant of time
