About Us


Prem Magnetics was organized in 1972 as the Magnetics Division of Prem Enterprises (a machine shop) to be a manufacturer of coils and transformers. The founders decided to emphasize quality long before quality got the attention it does today. In 1979, Prem Magnetics became a separate Illinois corporation.

After more expansion and growth, Prem Magnetics remains a leader in the transformer industry. In addition to our Illinois production facility, Prem operates a facility in Tecate, Mexico to manufacture products to the same quality standards. We are located roughly 40 miles northwest of Chicago, allowing access to anywhere in the world via numerous shipping hubs.

We are proud of the products we manufacture and look forward to demonstrating how Prem Magnetics can work for you.

Our Products are 100% Tested. Our mission is to provide products of only the highest quality. That is why we 100% Test every product we sell. We work hard to supply products that we are proud to offer to our customers.

Thank you again for visiting our website, and we look forward to doing business with you.

Our main office is open from 8:00 AM to 4:30 PM (Central Time) on Monday to Friday.
