Repair and rewinding of table and chuck magnets requires the same skill set as winding field coils for DC motors. The testing is also similar. These magnetic chucks are primarily used on large grinders. DC electro-magnets seem deceptively simple. They operate on the same principles as the common bar electromagnet and horseshoe electromagnet. The strength of this magnet is proportional to the ampere turns of the coil. The coil will produce north and south poles just as in a DC motor frame.
