21.3 Turning Effect on a Current-carrying Coil in a Magnetic
Help
3 factors that affect the turning effect forceon a current carrying coil in a d.c. motor
Inserting a soft iron core into the coil, Increasing the number of turn in the coil, Increasing the current in the coil
Which causing The speed of rotation d.c. motor increase....(Gravity -use soft iron core-Current decrease-decrease of strength of magnetic field)
use soft iron core
Name the effect that causes a coil of current-carrying wire in an electric motor to move (The electromagnetism effect-The motor effect -The magnetic effect)
the motor effect
