I am looking for a small electromagnet with a height of only 32 mm with cooling system and produce an out-of-plane magnetic field of about 2k Oe. Does any one know any brand which produces the small electromagnets.
It is difficult to give useful solution to it unless the elaborate details of the specific system is provided.
1) Please use electromagnet simulators eg. FEMM (http://www.femm.info/wiki/HomePage) to get an idea of the current requirements and the approximate dimension within which you want the design to be.
2) Also the details of the volume in which you want the field to be uniform has to be considered. This depends on the size of the sample on which you want field to be applied etc.
If you just need constant magnetic field, just try permanent magnets (Rare earth magnets can easily provide this field occupying much lesser space as well.)
Check with "GMW Associates" for electromagnets design/purchase.
