Air cooled coil electromagnet ?

AI Thread Summary
The discussion focuses on the feasibility of building an air-cooled solenoid electromagnet capable of producing a 4000 Gauss magnetic field. The researcher specifies the need for a chamber with a 4cm diameter and a coil length of 60cm to achieve uniformity in the magnetic field. Concerns are raised about the cooling requirements and the implications of using a specific size of wire for the coil. The researcher is looking for information on design and construction methods, emphasizing the necessity of air cooling due to operational constraints. Overall, the project aims to create a more efficient and manageable electromagnet system.

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 will be able to produce a 4000 Gauss magnetic field?

I am able to use either a high voltage or a strong current. I have some very serious lab equipment.

Where can I get Information about this kind of stuff?


Thanks.

There is some low cost design software available. I can't recommend any of it, but you can Google. But I see 2 points which raise doubts: (1) You say specific size. Do you mean small (implying small diameter wire)?; and, (2) the requirement for air cooled. Why? Is this 100% duty cycle?

I'm assuming the 4 kG is inside and you want it uniform. Is that right? How big a uniform volume?

4 kG is a piece of cake, but I might not be able to carry it.
 
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 chamber radius)
I can use relatively large radius wire and less turns or viced versa, whichever will give me better cooling.

second - the requirement for air cooling comes from above. we have a "Helmholz coil" system which works fine but is very inconvenient probably because of it's size and power consumption. anyway it's an order from above and I just have to tell them wether it's possible or not.

Thanks again for your answer.
 
Thread 'Motional EMF in Faraday disc, co-rotating magnet axial mean flux'
So here is the motional EMF formula. Now I understand the standard Faraday paradox that an axis symmetric field source (like a speaker motor ring magnet) has a magnetic field that is frame invariant under rotation around axis of symmetry. The field is static whether you rotate the magnet or not. So far so good. What puzzles me is this , there is a term average magnetic flux or "azimuthal mean" , this term describes the average magnetic field through the area swept by the rotating Faraday...
It may be shown from the equations of electromagnetism, by James Clerk Maxwell in the 1860’s, that the speed of light in the vacuum of free space is related to electric permittivity (ϵ) and magnetic permeability (μ) by the equation: c=1/√( μ ϵ ) . This value is a constant for the vacuum of free space and is independent of the motion of the observer. It was this fact, in part, that led Albert Einstein to Special Relativity.
