Abstract
A powdered metal electromagnetic is provided that has much less variance between units, increased frictional drag, reduced wear of itself and the brake drum disk during use and an increased resistance to moisture due to the use of a donor material that increases performance and reliability. In addition it can withstand much higher surface speeds while producing higher frictional drag.
