Magnetic effect of electric current 1) Magnetic effect of electric current was the first discovered by Oested in 1820. 2) Magnetic effect of current is a phenomenon by virtue of which an electric current in a conductor produces a magnetic field around it. Magnetic effect of electric current 3) The magnitude of the magnetic field produced depends upon the magnitude of current passing through conductor. 4) The direction of magnetic field produced depends upon the direction of current in the conductor . 5) The magnetic field produced due to a current carrying conductor is always in a plane perpendicular to the plane of the conductor. 6) When an electric current is passing through a conductor only magnetic field is associated with the conductor but there is no electric field, since the conductor is electrically neutral. 7) When an electric charge is moving in free space, both, electric and magnetic fields are produced, whereas a stat...
