Abstract
A high torque electromagnetic device such as a moving magnet galvanometer includes a composite electromagnetic coil. The composite electromagnetic coil includes two pancake-shaped coil parts made using a rectangular conductor having a width and a thickness, wherein the winding formed for each pancake-shaped coil part has the width oriented in a direction substantially normal to the initially flat face of the pancake-shaped coil part. Each pancake-shaped coil part is subsequently shaped to a shape different from the initially flat shape. The coil parts are superposed and electrically connected to form a single tightly packed unit.
