Question

15. AB is a current carrying conductor in the plane of the paper as
shown in Figure 13.7. What are the directions of magnetic fields
produced by it at points P and Q? Given r, > ry, where will the
strength of the magnetic field be larger?​

Answer 1

Answer:

At Q - Out of the plane of paper

At P - Into the plane of paper

The Magnetic field will be greatest at Q.

This is because B[Magnetic field]∝1/r[Distance]

Or the strength of the magnetic field is inversely proportional to distance.
