Hi,(adsbygoogle = window.adsbygoogle || []).push({});

I like to research the possibility to build an electromagnet that is quit big and has a lot of strength. As I really don't know much about magnetism, I don't see how to start with this.

Anyone that please can help me with some formulas?

I like to make a sort of excel or matlab program where I can put in some numbersSo the program gives me how big my electromagnet should be and of course how much electricity it takes per sec.

- magnetic contact area
- desired magnetic strength

Thx
