A very long solenoid of radius a and height h has N closely wound turns of coil. Suppose there is an increasing current I(t) that runs through the coils. Consider a point P inside the solenoid (i.e. at r < a).
(a) Find the magnetic field at P.(b) Find the electric field at P.(c) Find the Poynting vector at P.(d) What is the total power into/out of the solenoid?Please show steps
