Effect of Earth’s Magnetic Field on Wave Propagation
1. The average magnetic field of the earth is about 40 A/m. The earth’s magnetic field causes the electrons to trace complicated trajectories with cyclotron or gyrofrequency fg = l.4 MHz at H = 40 A/m. 2. The earth’s magnetic field (B) exerts a deflecting force on the moving electrons. The magnitude of this force …
