Why is the iron core of a transformer made laminated instead of being ...
Eddy currents are the loops of electrical current induced within conductors by a changing magnetic field in the conductor, due to Faraday's law of induction.
Making the core out of thin laminations parallel to the magnetic field with insulation between them reduces the eddy currents and thus also reduces the energy loss due to eddy currents.
