Electric load Q is evenly distributed on a rotating radius R, with a circular frequency ω (linear velocity v = ωR), around an axis, which passes through its center and is perpendicular to its plane. a) Examine the fields in the space. Are they time-dependent? b) Calculate the ratio of the electric to the magnetic field at the point P with x = R and comment on the result. c) With the same center as the radius R loop a small circular conductive loop is placed, radius r << R, with their levels forming an angle φ. Calculate the coefficient of mutual induction M of the system, making reasonable approaches, based on the relation of rays. c = (ε0 μ0) ^ (1/2
