Effects of electropluse and direct current on supercooling of the Wood′s alloy were examined based on the some popular electromagnetic field theories. The results show that electro-pulse can reduce the supercooling of the Wood′s alloy

while direct current has alternative effects on the supercooling

which can increase the supercooling with low direct current

and reduce supercooling with high direct current. All the experimental results are relative to the selected material

and applied electric parameters have applicable scope.
