Question

what are Eddy currents . Give an experiment to explain this their origin.?

Answer 1

Answer:

Eddy currents are loop of electrical current induced within conductors by changing magnetic field in the conductor according to faraday's law of induction.

Explanation:

use an AC current in a solenoid with an ammeter in the circuit. drinking flat weight of towards a coil. the current show increased. and non conductor circle, Steel magnetic surface, and Aluminium surface to surface made up of several smaller pieces separated by a thin insulating sticks used in each case observer effect upon the electric current in the primary. the higher currents are created the loss in Eddy currents

$\Large\bold\star\underline{\underline\textbf{Eddy currents\:}}$

→ Eddy currents are the circulating currents which are produced in a conductor when the magnetic flux linked with the conductor changes.

» This current leads to the heating of the conductor and hence energy is lost.

$\Large\bold\star\underline{\underline\textbf{Experiment\:}}$

→ Note : Check the necessary picture also that is related to the ans (provided with answer)

→ Consider a solenoid connected to the source of alternating current. Let an aluminium disc be placed an coil. The alumihium disc remains placed on the column when the switch 'S" is off.

→ When the current is allowed to pass through the solenoid, the disc is thrown up. Current is induced in the disc which is eddy current. This induced current produces a magnetic field which opposes the growing magnetic field of solenoid. Thus the disc jumps up.
