Thanks.
First - about the uniformity, I need the chamber to be 4cm in diameter and the coil should be 60cm long (or two coils of 30cm each with a slit between them), so this will provide me with a certain uniformity that I believe is satisfactory for my needs. (the length is >> than the...
Air cooled coil electromagnet ?
Hi. I'm a (very) Junior researcher
I'm trying to biuld a solenoid electromagnet (air bore, not metal), But I need it in a specific size and most important I have to have it AIR COOLED (by fan or compressed air).
Does anybody know if such an electromagnet...

isn't the 1/2 factor a result of the chain rule?
thank you.
