Abstract
A solenoid coil assembly comprises a bobbin containing an electromagnetic coil thereon, and a magnetically permeable conductor for conducting magnetic flux issued by said coil when energized. The magnetically permeable conductor is in the form of plural magnetically permeable U-shaped wires circumferentially arranged around the bobbin with one side of each wire disposed radially inwardly of the coil and the other side of each wire disposed radially outwardly of the coil. The sides of the wires pass through pre-formed holes in the bobbin.
