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.
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.
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 ...
Definition of Inductance. In electromagnetism and also in the electronics, inductance is the tendency of electrical conductors for opposing a change in the electric current that flows through it. Nonetheless, the flow of the electric current generates a magnetic field throughout the conductor whose strength is depending on the magnitude of the ...
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.
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.
Define electromagnetic induction? Solution. Verified by Toppr. Electromagnetic induction is the production of emf across an electrical conductor in changing magnetic field. This phenomenon was discovered by Michael Faraday.

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 ...
Electromagnetic induction. The current is a result of an emf induced by a changing magnetic field, whether or not there is a path for current to flow. Faraday's apparatus for demonstrating that a magnetic field can produce a current. A change in the field produced by the top coil induces an emf and, hence, a current in the bottom coil.
