Hello I need to make an electro magnet as strong as my M42 magnet . So what size magnet wire/ how many turns / and what voltage would I need to achieve the same strength as the 2” x 1” x 1-2” thick 42 ?

Correction my N42 magnet

 

Amperes multiplied by turns until achieving what you want.

 

What material do you propose to use for the electromagnet core?
