Question

how can hysteresis loss be minimized

Answer 1

Hence hysteresis loss can be reducedby using material having leasthysteresis loop area. Hence silicon steel or high grade steel is used for manufacturing of transformer core as it is having very less hysteresis loop area. You can laminate the core. Since laminating the core would have less eddy currents in the core.

Answer 2

The formula for hysteresis loss is..........(SEE THE FORMULA IN THE IMAGE) 
​
where Ph is the hysteresis loss,  
n is the hysteresis coefficient,  
f is frequency, 
Bmax is the maximum flux density. 
From this equation to reduce hysteresis, we can see that frequency is constant and 
Bmax varies from material to material but that too not over a wide range. 
Hence only thing that can be reduced is the hysteresis coefficient. It depends on the material, so we have to choose a material which has low hysteresis coefficient and high permeability.
