will iron filings get attracted to an electromagnet when it is switched on or off? Explain

Answer» <p>Withelectromagneticwaves, it's just that the electric and magnetic fields oscillate and that is the source of energy of the wave.</p><p> So the fields aren't being emanated from any magnetic material, so they are blind to all magnetic material. </p><p>Light is anelectromagneticwave, but itdoesnot attract.</p>
