In which situation shown in Figure will the electromagnetic wave be more successful in inducing a current in the loop? Explain.
A long straight conducting rod (orwire) carries a linear charge densityλof +2.0μC/m. This rod is totally enclosed within a thincylindrical shell of radius R, which carries alinear charge density of - 2.0μC/m.
Communication with submerged submarines via radio waves is difficult because seawater is conductive and absorbs electromagnetic waves. Penetration into the ocean is greater at longer wavelengths, so the United States has radio installations that tran..
