Question

In Fig. 285, an irregular loop of wire carrying a current lies in the plane of the paper here. Suppose that now the loop is distorted into some other shape while remaining in the same plane. Point P is still within the loop. Which of the following is a true statement concerning this situation? A) It is possible that the magnetic held at point P is zero. B) The magnetic field at point P will not change in magnitude when the loop is distorted. C) The magnetic field at P will not change in direction when the loop is distorted. D) The magnetic field at point P will always lie in the plane of the paper. E) None of these are true.

Explanation / Answer

The only correct option from the whole options is -
The direction of Magnetic field at P will not change when the loop is distorted.

The direction will be given by Right hand rule, and Magnetic Field wiil be out of the plane of paper.
