Question

Why is the iron core of a transformer made laminated instead of being in one solid piece?

Answer 1

Iron Core of Transformer

1. In response to the fluctuating magnetic field, the eddy currents in the conductor result in more energy loss, converting the kinetic energy to thermal energy.
2. A whirling current that forms in a conductor in reaction to a fluctuating magnetic field is known as an eddy current.
3. The eddy currents cause energy losses due to their opposing tendency.
4. The eddy currents can be prevented by laminating the iron core of a transformer.
   

Hence, the iron core of a transformer is laminated to prevent the eddy current and decrease the losses.
