Detailed Solution
Download Solution PDFMagnetic effect of current:
- The magnetic effect of electric current was discovered by H.C. Oersted in 1820.
- He observed that the flow of electric current through a conductor produces a magnetic field around it.
The magnetic effect of current was proved by an experiment which was as under:
- Initially, the magnetic needle was put on the axis of the magnetic meridian. When a current flows through the circuit, the needle got deflected in the direction of the electric current.
- And when the direction of the electric current was reversed, the needle got deflected in the opposite direction.
- This proved that the magnetic effect was produced by the electric current and the electric field is a source of the magnetic field and vice-versa.
