Question

question 7 of 10
in which direction does the magnetic field in the center of the coil point?
a. left
b. down
c. right
d. up

Explanation:

Step1: Apply the right - hand rule

Grasp the coil with the right hand. Curl the fingers in the direction of the current. The thumb points in the direction of the magnetic field inside the coil (at the center).
Assume the current direction as per the coil's winding (from the given figure's arrow - like indication of current flow). When we apply the right - hand rule, if we consider the current entering from one side and exiting from the other, the thumb (representing the magnetic field direction at the center) points to the left.

Answer:

A. Left
