Why is a soft iron core used in a transformer?
(N/A) soft iron core is used in a transformer for two primary reasons:
$1$. High Magnetic Permeability: Soft iron has high magnetic permeability,which allows it to easily magnetize and demagnetize. This ensures that the magnetic flux produced by the primary coil is efficiently linked to the secondary coil,minimizing flux leakage.
$2$. Low Hysteresis Loss: Soft iron has a narrow hysteresis loop,which means the energy dissipated as heat during each cycle of magnetization and demagnetization (hysteresis loss) is very low. This increases the overall efficiency of the transformer.
