Walker Scientific Electromagnet

I have a Walker Scientific HF-12H Electromagnet available for donation. The magnet has 12″ diameter flat pole faces and a 4.5 inch gap. It has a standard H-frame style yoke that rests on a cradle that positions the yoke at a 45 degree angle typical for EPR. The magnet is 30 years old and was always used with a closed, deionized water cooling system.
