Answer 1

The direction of a magnetic field at any point is the direction of the force on a north pole at the point. The magnetic effect of an electric current was discovered by Hans Christian Oersted in 1820. To demonstrate the effect, a plotting compass is placed close to a long straight wire which is carrying current.
