| Electromagnetic relays are devices that connect and disconnect contact
points physically using an electromagnet.The magnetic attraction that activates
the relay is generated by the magnetomotive force, which is expressed by
the product of coil turns and current.The operating time can be calculated
from the magnetic attraction at the moveable core using an equation of
motion.This example presents the use of a magnetic field analysis to evaluate
the operating time of an electromagnetic relay driven by direct current
accounting for the eddy currents. |
