Hysteresis: The phenomenon of lagging of magnetic induction behind the magnetizing field is called Hysteresis and called “delayed”.
Magnetic field due to a long straight current carrying conductor: As shown in fig. consider straight conductor XY carrying current I. We wish to find its magn
Moving coil Galvanometer: A galvanometer is a device used to detect current in a circuit.
Principle: If a current carrying coil placed in a magnetic field experiences a torque, the magnitude of which depends on the strength of current.
Magnetic force on a moving charge: the electric charges moving in a magnetic field experiences a force F such that
(i) The force is proportional to
Ampere’s Circuital law: The line integral of the magnetic field around any closed circuit is equal to the µ0 times the total current l threading or passing through the closed circuit.
Mathematically,
Electric potential: The electric potential at a point in an electric field is the amount of work done in moving charge from infinity to that point.
Biot-Savart law: According to Biot-Savart law, the magnitude of the field dB is
Directly proportional to the current I through the conductor. i.
Torque on current loop in a uniform magnetic field:
An ideal simple pendulum consists of a heavy point mass body suspended by a weightless, inextensible and perfectly flexible string from a rigid support about which it is free
Equipotential surface: Any surface that has same electric potential at every point on the surface of the conductor known as equipotential surface.
Whenever there is a relative motion between a source of sound and the listener, the apparent frequency of sound heard by the listener is different from the actual frequency of
Position
The position of a particle refers to its location in the space at a certain moment of time.
It is concerned with the question - “ where is the particle at a particular instant of time ? ”
De-Broglie’s Equation:-
According to de-Broglie a moving particle can be associated with a wave. So the waves associated with a moving materi
