Electrostatics

Whenever current flows through a coil, the self−inductance opposes the growth of the current. Hence, some work has to be done by external agencies in…

Since self-inductance is related to the magnetic field produced by a current, any configuration of conductors possesses self-inductance. Inductance is attained by a coil due…

Coefficient of self induction of the ratio of the electromotive force (emf) produced in a circuit by self-induction to the rate of modify of current…

The property of a coil which enables to produce an opposing induced emf in it when the current in the coil changes is called self…

This is a phenomenon in which certain organic or inorganic compounds have the property of rotating plane polarised light. The compounds which exhibit this property…

Whenever there is a change in the magnetic flux linked with a closed circuit an emf is produced. This emf is known as the induced…

Faraday’s Laws of Electromagnetic Induction Based on his studies on the phenomenon of electromagnetic induction, Faraday proposed the following two laws. First law Whenever the…

The Russian scientist H.F. Lenz in 1835 discovered a simple law giving the direction of the induced current produced in a circuit. Lenz’s law states…

Lenz’s Law– a Consequence of Conservation of Energy Copper coils are wound on cylindrical cardboard and the two ends of the coil are connected to…

Fleming’s Right Hand Rule The forefinger, the middle finger and the thumb of the right hand are held in the three mutually perpendicular directions. If…
