What Happens to a CurrentCarrying Wire in a Magnetic Field?

Because the magnetic field created by the electric current in the wire is changing directions around the wire, it will repel both poles of the magnet by bending away from the wire. Depending on which pole is up (a mark on your magnet might tell you which is north or south), the wire will bend away from the magnet or farther into the “U.”Chat Online
