. 3. An electromagnetic plane wave of (angular) frequency w is traveling in the r direc- tion through the vacuum. It is polarized in the y direction, and the amplitude of the electric field is E (a) Write down the electric and magnetic fields, E(r, y, z, t) and B(x, y, z,t).

A conducting bar of length D rotates with angular frequency w about a pivot P at one end of the bar (see the figure). The other end of the bar is in slipping contact with a stationary conducting wire in the shape of a circle (we only show a small part of that circle to keep the drawing simple). Between point P and the circular wire there is a resistor R as shown. Thus the bar, the resistor and the...
