Abstract
An inductor such as a fluorescent lamp choke comprises a bobbin carrying a winding, a laminated core, and a sheet metal casing consisting of two parts which have interengaging flanges and grooves along four parallel edges which are slid together and subsequently bent over and pressed against end faces of the core to secure the parts of the casing together so that they exert pressure on the core from all sides.
