- 1(current)
Q. No.Given below are two statements:
| Assertion (A): | No electric current will be present within a region having a uniform and constant magnetic field. |
| Reason (R): | Within a region of uniform and constant magnetic field the path integral of the magnetic field along any closed path is zero. Hence from ampere circuital law \(\varphi \overrightarrow{\mathrm{B}} \cdot \overrightarrow{\mathrm{dl}}=\mu_0 1\) (where the given terms have usual meaning), no current can be present within a region having a uniform and constant magnetic field. |
| 1. | Both (A) and (R) are true and (R) is the correct explanation of (A). |
| 2. | Both (A) and (R) are true but (R) is not the correct explanation of (A). |
| 3. | (A) is true but (R) is false. |
| 4. | Both (A) and (R) are false. |
