Problem
Oscillating E and B * In the central region of a solenoid that is connected to a radio-frequency power source, the magnetic field oscillates at 2.5⋅106 cycles per second with an amplitude of 4 gauss. What is the amplitude of the oscillating electric field at a point 3 cm from the axis? (This point lies within the region where the magnetic field is nearly uniform.)
