The current at which a magnetic-type overload relay tends to trip may be decreased by raising the plunger further into the magnetic circuit of the relay. This action ___________. A. reduces magnetic pull on the plunger and requires more current to trip the relay B. reduces magnetic pull on the plunger and requires less current to trip the relay C. increases magnetic pull on the plunger and requires more current to trip the relay D. increases magnetic pull on the plunger and requires less current to trip the relay
