A conducting loop is lying flat on the ground. The north pole of a bar magnet is grought down toward the loop. As the magnet approaches the loop, will the magnetic field created by the induced current point up of down?
up
down
neither because there is no induced current
we must first know whether the approaching magnet is a bar magnet, or a horseshoe magnet.
Consider the same conducting loop and approaching magnetic north end of a bar magnet. As the magnet approaches the conducting loop, will the induced field of the loop pull on the bar magnet or push against it?
pull on magnet
push against manget
neither, as there is no induced magnetic field.
