A single current carrying loop of wire carrying current II flowing in anticlockwise direction seen from +vez+ vez direction and lying in xyxy plane is shown in figure. The plot of \overset{^}{j} component of magnetic field (By)( By ) at a distance aa (less than radius of the coil) and on yzyz plane vszvsz coordinate looks like

Options

  1. AGiven below are two statements: One is labelled as Assertion A and the other is labelled as Reason R: Assertion A: p K
  2. BGiven below are two statements: One is labelled as Assertion A and the other is labelled as Reason R: Assertion A: p K
  3. CGiven below are two statements: One is labelled as Assertion A and the other is labelled as Reason R: Assertion A: p K
  4. DGiven below are two statements: One is labelled as Assertion A and the other is labelled as Reason R: Assertion A: p K

Correct answer

C. Given below are two statements: One is labelled as Assertion A and the other is labelled as Reason R: Assertion A: p K

Step-by-step solution

A single current carrying loop of wire carrying current I flowing in anticlockwise direction seen from + vez direction

Magnetic field in plane of coil is By=0{B}_{y} = 0

The direction of \overset{^}{j} component of magnetic field By{B}_{y} is opposite of each other in –z– z and +z+ z positions.

So, the variation of magnetic field is shown below.
