    Electromagnetism is a branch of physics involving the study of the electromagnetic force, a type of physical interaction that occurs between electrically charged particles.
    Magnetism is created when electricity flows through metals. The magnetic force starts when the electricity flows, and stops if the electric current is disconnected. This kind of magnetism is called electromagnetism, and it is very useful for making magnets that can be switched on and off.
    , AB is a wire lying in the north- south direction and connected to a battery through a rheostat and a tapping key. A compass needle is placed just below the wire. It is observed that
    that a current carrying wire produces amagnetic field around
    Right hand thumb rule determines the direction of magnetic field around a current carrying wire.
    It states that if we hold the current carrying conductor in right hand such that the thumb points in the direction of flow of current, then the fingers encircle the wire in the direction of the magnetic fields lines.
    ELECTROMAGNETIC INDUCTION:
    Whenever there is a change in the number of magnetic field lines linked with a conductor, an electromotive force (e.m.f.) is developed between the ends of the conductor which lasts as long as there is a change in the number of magnetic field lines through the conductor. This phenomenon is called the electromagnetic induction.
    Faraday formulated the following two laws of electromagnetic induction -
    Whenever there is a change in magnetic flux linked with a coil, an e.m.f. is induced. The e.m.f. induced lasts so long there is a change in the magnetic flux linked with the coil.
    The magnitude of e.m.f. induced is directly proportional to the rate of change of magnetic flux linked with the coil. If magnetic flux changes at a constant rate,a steady emf is produced
    The magnitude of induced e.m.f. in a coil depend on following two factors -
    The rate of change in magnetic flux with each turn of coil, and
    The number of turns in the coil.
    When a conductor is moved in a varying magnetic field, then Fleming's right hand rule determines the direction of current induced in the conductor.
    Fleming's right hand rule - Stretch the thumb, central finger and forefinger of your right hand mutually perpendicular to each other. If the forefinger indicates the direction of magnetic field and the thumb indicates the direction of motion of the conductor, then the central finger will indicate the direction of induced current.
    According to Lenz's law, the direction of induced e.m.f. (or induced current) is such that it opposes the cause which produces it.
    Lenz's law is based on the law of conservation of energy. It shows that the mechanical energy is spent in doing work against the opposing force experienced by the moving magnet, and it is transformed into the electrical energy due to which current flows in the solenoid.
    An A.C. generator is a device which converts the mechanical energy into the electrical energy using the principle of electromagnetic induction.
    Principle - In a generator, a coil is rotated in a magnetic field. Due to rotation, the magnetic flux linked with the coil changes and therefore an e.m.f. is induced between the ends of the coil. Thus, a generator acts as a source of current in an external circuit containing load when connected between the ends of it's coil.
    Use - We use a.c. generator in our house as an alternative source of electricity when electric supply from mains is not available.
