10. A long-haired cat walks across a carpet in winter and picks up an excess charge of 90°C. The cat then sees a mouse and chases the mouse in a circle of radius 1.3 m at a speed of 8m/s. a. Find the magnetic field produced by the charged cat (on an axis through the center of the circle) (Hint: use the Biot-Savart law adapted for point charges) b. What is the frequency of the cat? c. Write electric and magnetic fields produced by the charged cat, assuming the waves are plane waves (even though they are not really!) d. What is the intensity of the cat's EM field?
