Electromagnetic This is a process of production of electricity (electric current) by the variation of Induction magnetic field across the conductor is called Electromagnetic Induction . Faraday’s Law of First law - EMI Whenever magnetic line of forces change across conductor ,an e.m.f. is induce in it .This induced e.m.f. last so long as the change in magnetic field continues. Second law- The magnitude of the induced e.m.f. is directly proportional to the rate of change of Magnetic flux linked with the conductor (or coil). Direction of Fleming -Hand Rule It use to determine the direction of induced current . – induced current According to this rule : three finger of right hand arrange mutual perpendicular “if in such a way that thumb points in the direction of motion of conductor, forefinger points direction of magnetic field, then middle finger indicate direction of induced current .” Activity To draw magnetic line of forces by a bar magnet. To show force on a current carrying conductor place in magnetic field.
