Solution: Sinusoidal electromagnetic waves from a radio station pass perpendicularly through an open window that has area 0.200 m2. At the window, the magnetic field of the wave has amplitude Bmax = 7.00 x 10-10 T. How much energy does the wave carry through the window in 2.00 minutes? (Note: ε0 = 8.854 x 10-12 C2 / N•m2 and μ0 = 4π x 10-7 T•m/A)
