Eddy currents are loops of electric current induced within conductors by a changing magnetic field in the conductor due to faraday s law of induction.
This means that a steel laminated core can carry a magnetic flux 1500 times better than that of air.
The iron core transformer has higher permeability thus it is applied in transformer in place of air core in modern transformer.
Enphase split core current transformer 200a for consumption metering 4 5 out of 5 stars 4 4 product ratings enphase split core current transformer 200a for consumption metering.
The eddy currents cause energy to be lost from the transformer as they heat up the core meaning that electrical energy is being wasted as unwanted heat energy.
Reduce eddy current losses.

Laminations are provided to reduce eddy currents.
The core is laminated to reduce these to a minimum as they interfere with the efficient transfer of energy from the primary coil to the secondary one.
Most transformer cores are constructed from low carbon steels which can have permeabilities in the order of 1500 compared with just 1 0 for air.
