How does the voltage applied to the electric motor affect the coil's number of rotations and its rotational direction

Need in all of themmm only answer if you know plsssss

An electric current is flowing through the cord below.what will happen to this current if a magnet is brought near the cord? a. the electric current will stop flowing. b. it will exert a force on the voltage. c. the resistance of the wire will decrease. d. it will exert a force on the electric current.

If the force applied to an object remains constant, is more power needed for the object to move faster ? explain
