A scientist runs an electric current along a wire. A magnetic compass is placed nearthe wire. The scientist observes that whenever the current is turned on, the compass needle moves. Why does the compass needle move? Using the formula KE = 4 mv? (where m= mass and v= velocity), what is the kinetic energy of a 8 kilogram ball
traveling at 3 m/s?

The current creates an electric field around the wire

The current creates a magnetic field around the wire

The current adds electric charge to the compass needle

The current increases the force of gravity on the compass needle
