Question

Write any one application of faraday's law of induction in daily life ?

Answer 1

1)Transformers are works on the principle of electromagnetic production.
2) Electrical generators works on the principle as electro magnetic induction.
3) Security check at airports. railway stations.
4) Tape recorders use to record voices or listen songs works on the principle of electromagnetic induction.
5) ATM cards and swiping machines are also the application of law of electro magnetic induction.

Answer 2

Eddy currents
An eddy current is a swirling current set up in a conductor in response to a changing magnetic field. By Lenz¹s law, the current swirls in such a way as to create a magnetic field opposing the change; to do this in a conductor, electrons swirl in a plane perpendicular to the magnetic field.
Because of the tendency of eddy currents to oppose, eddy currents cause energy to be lost. More accurately, eddy currents transform more useful forms of energy, such as kinetic energy, into heat, which is generally much less useful. In many applications the loss of useful energy is not particularly desirable, but there are some practical applications. One is in the brakes of some trains. During braking, the metal wheels are exposed to a magnetic field from an electromagnet, generating eddy currents in the wheels. The magnetic interaction between the applied field and the eddy currents acts to slow the wheels down. The faster the wheels are spinning, the stronger the effect, meaning that as the train slows the braking force is reduced, producing a smooth stopping motion.
