You have a loop of copper wire connected to a light bulb. You quickly pass a permanent bar magnet through the center of the loop. What happens?1- The loop pulls the magnet on through.2- Current flows in the loop.3- The magnet becomes demagnetized by the loop.4- The magnets poles are reversed by the loop
The moving magnetism will exert a force on the electrons in the wire loop - a current will be created in the loop Answer 2
that's an somewhat exciting question. i think of others are lacking the element. i think what this man or woman is making an attempt to ask is that in case you plate copper cord with silver will the cord take on the extra conducive residences of silver at much less value. want the cord be good silver? in case you plated copper with silver approximately .001 of an inch it can be a rather affordable technique. additionally you does no longer might desire to apply nickel. Silver will bond to copper rather properly. Any Physics majors available want to attempt to finger (determine) this one? i'm a ME i'm no longer qualified to do the mathematics in this one. even however i will make a prototype!
