Can I turn 1.2 volts?

Question

into a .1 T (100 gauss) electromagnet. Is it even possible? Yes or no

How do I do this?

Answer 1

I'll rephrase your question a bit..

Can a 1.2V source be used to drive an electromagnet? Yes of course.

Is a 1.2V source good match for an electromagnet? Probably not.

You need around 80 Ampere Turns to produce a 0.1T field in a 1mm air gap. So if you were to use 80 turns of wire with each turn 15mOhm then you have an electromagnet that is matched to your 1.2V source and will provide a 0.1T field. I haven't bother to work out the cross section of the wire. It is only an issue if the space for the winding is constrained.

Answer 2

MMMMMM, you would definitely need a super conducter to get enough current out of 1.2V. Or use a transformer to pump up the voltage to your magnet, but then you will still have to draw a huge current from your source to drive the transformer. But I don't think you will be able to get a 1000 gauss magnet with any readily available materials from a 1.2V source
