Electromagnetic Induction and its Applications. Electromagnetic Induction or Induction is a process in which a conductor is put in a particular position and magnetic field keeps varying or magnetic field is stationary and a conductor is moving. This produces a Voltage or EMF (Electromotive Force) across the electrical conductor.
Magnetic moment. Answer: A. Self-inductance is that phenomenon in which charge in electric current in a coil produces an induced emf in the coil itself. Q2. Two coils A and B have L= 2×10 -2 Henry. If the current in the primary is i = 5 sin 10πθ then maximum value of emf induced in coil B is: Π volt.

Faraday’s law of induction is an essential law of electromagnetism anticipating how an attractive field will connect with an electric circuit to deliver an electromotive power (EMF)— a wonder known as electromagnetic enlistment. This relates the pace of progress of attractive motion through a circle to the extent of the electro-motive force ...
Solution. Self-inductance of a coil is defined as the phenomenon due to which an emf is induced in a coil when the magnetic flux of coil , linked with the coil changes or current in coil changes . Its S.I. unit is H enry(H) .
Give two definitions of mutual inductance and write its unit. Solution. Verified by Toppr. (i) Mutual inductance of two coils is equal to the e.m.f induced in one coil when when rate of changes of current through the other coil is unity.
L = μoμrN 2I A l. It is clear that self inductance of solenoid depends upon the following factors: (1) On relative permeability of material inside the solenoid: If a soft iron core placed inside the solenoid, the magnetic flux linked with the solenoid increased hence, self inductance of the solenoid will also increases.
Eddy currents. An eddy current is a current set up in a conductor in response to a changing magnetic field. They flow in closed loops in a plane perpendicular to the magnetic field. By Lenz law, the current swirls in such a way as to create a magnetic field opposing the change; for this to occur in a conductor, electrons swirl in a plane ...
Moreover, the expression of the formula of Faraday’s law is as: <tbody. ε =−NΔϕΔt. ε is the electromotive force. Where, Φ refers to the magnetic flux. N shows the number of turns. The negative sign indicates that the change in the direction of magnetic fields and the direction of the induced emf have opposite signs.
Explain with the help of a diagram. Magnetic Induction: The property by which an ordinary piece of iron acquires magnetic properties temporarily due to the presence of another magnet close to it, is known as magnetic induction. Take a tong nail. Put it on the arm of a stand. Spread some iron pins on the base of the stand.
