I know that an electro magnet can have a higher tesla rating when you increase the current or the times revolved around the core but I was wondering if someone could give me an equation or set of equations involving the lenght of wire, gauge of wire, current, cross sectional area of the wire, wire resistance, number of windings and the diameter of the core and the windings. In terms of teslas just plain and simple. For example to achieve 10^-2 teslas what variables would I need to know. Equations or websites would be great, I cant seem to find exactly what I'm looking for.(adsbygoogle = window.adsbygoogle || []).push({});

thanks very very much
