Question

which of the following has no effect on the size of turning effect of coil of an electric motor?
a )the amount of current in the coil

b) the direction of current in the coil

c) the number of turns in the coil

d) the distance of the magnetic field​

Answer 1

Answer:

the direction

Explanation:

direction would just change the motion of turning from clockwise to anticlockwise, not change the size.  

Answer 2

The following has no effect on the turnaround size of the electric car coil is:

• The size of the calculated e.m.f. depending on the coil turning value.
• The size of the calculated e.m.f. it does not change as the coil turns.
• Wrapping the coil in a soft iron cylinder makes no difference to the captured e.m.f.
• Two forces acting in opposite directions on both sides of the coil form a pair and produce the effect of turning on the coil.
• Power is generated when the magnetic field due to the current in the coil meets the outer magnetic field to produce two catapult fields around the coil.
