The force carried by the plunger of the door chime of given, Ask an Expert

Engineering

The force carried by the plunger of the door chime of given figure is determined by

Where dφ/dx is the rate of change of flux linking the coil as the core is drawn into the coil. The greatest rate of change of flux will occur when the core is ¼ to 3⁄4 the way through. In this region, if changes from 0.5 x 10^-4 Wb to 8 x 10^-4Wb, what is the force carried by the plunger?
