I'd like to produce AC fields with my magnet.
   Most laboratory electromagnets will not produce AC fields. This is because they use a solid steel yoke. To produce an AC field you would need a laminated magnet such as the GMW 5403AC.

What if I want a vertical field direction?
   To get a vertical field direction, you must mount the magnet on it's end. We provide a vertical mounting bracket for most of the magnets that we offer.

What is the warranty?
   The warranty on all GMW products is one year.

What if I want an axial hole in one or both poles?
   Yes, we can machine axial holes in to the pole pieces. The exact geometry must be provided by the customer, and it will affect the field uniformity. It is best to keep the holes as small as practical.

Can I get GMW to install my magnet?
   Yes, GMW installs magnet systems worldwide.
