why is it that electromagnetic wave cannot travel through conductors?

Answer 1

I'm not sure what you mean. Electromagnetic waves travel quite well through metallic conductors, especially copper, silver, and gold. Radio signals travel through cables from the transmitter to the antenna.

Answer 2

I think you are wrong because it can travel and this the principle of screening which is to protect sensitive electronic instruments by surrounding it by a good conductor so electromagnetic waves will leave the inst and go through the conductor

Answer 3

Conductors conduct because they have free electrons that move along through the conductor lattice. As charged particles, they also can move when subjected to external magnetic fields, which induce current, as well as electric fields which push/pull on the electrons. Hence, EM fields are absorbed, more or less, by conductors, and their energies are consequently not transmitted or passed through conductors. Radar is an interesting energy in the case of flying aircraft, particularly Stealth aircraft. The coating absorbes and transmits the energy based on dipole characteristics as opposed to reflecting it.

Answer 4

they could. The magnetic waves are to blame for electric powered turbines to furnish electricity, for electric powered autos to apply electricity to run and also transformers use magnetic waves to move one type of electricity to a distinct. i'm particular there are more advantageous makes use of. even as magnetic waves flow via a conductor (wire) an electric powered present day is produced in that conductor.

Answer 5

I think he means that EM waves cannot *penetrate* conductors. For example, putting magnetic tapes or disks inside a metal box will protect them from external magnetic fields. (There must be a point where this breaks down for thin boxes and strong fields, though.)
