Abstract
A coil for magnetizing an article. The coil includes a cooling coil component and an electric coil component. An elongate electric coil component is placed with its center along a bobbin, wherein one end is wound in one direction around the bobbin and the other end in the other direction. The cooling coil component includes a disk-like member in which a passage is formed for carrying a fluid coolant. The disk-like member is 'C' shaped to substantially prevent the flow of eddy currents. Electric coil components disposed at the ends of the coil are provided with a greater number of windings to make the magnetic field in the coil more uniform.
