Question

Explain Eddy current


in alternating current​

Answer 1

Explanation:

hey mates here is your answer of $\huge{\boxed{\boxed{\red{\ulcorner{\mid{\overline{\underline{\bf{Eddy :\ current}}}}}\mid}}}}$

Eddy current is induced in a conductor when it is placed in a changing magnetic field or when aconductor is moved in a magnetic field and/or both. Any imagined circuit within the conductor will change its magnetic flux linkage and the subsequent induced emf. will drive current around the circuit.Thus the alternating magnetic flux induces eddy currents in the iron core and causes heating. The effect is reduced by laminating the core, i.e., the core is made of this sheets of iron with insulating sheets between them so that the circuits for the eddy currents are broken.

Answer 2

Answer:

When a conductor is placed in the changing magnetic field, the induced current in the conductor is termed as Eddy current. We can define it as: Eddy currents are loops of electrical current induced within conductors by a changing magnetic field in the conductor according to Faraday's law of induction.
