Hey there ❤❤
Ur answer is here ⤵✌
Answer => No , the bar will not retain magnetism. this is because the Curie temperature (358° C) , Nickel becomes paramagnetic and loses its magnetism on heating further.
when cooled in magnetic field free space, the bar does not retain its magnetism.
hope it's help you ✌❤
