What is the direction of the magnetic field at point P in the figure? (P is on the axis of the coil.)

Expert Solution

Strategy:

We use Right Hand Rule -3 to find the direction of magnetic field due to a solenoid at point P is on the axis of the coil.

Reason:

From the Right Hand Rule -3 curl the fingers of your right hand inward toward the palm, following the current around the loop. Your thumb points in the direction of the magnetic field in the interior of the loop.

So the direction magnetic field is towards right.

That is represented symbolically →.

Option (d) is correct answer.
