Ampere's law is applied over any:
Correct answer: D. Closed path
- A. Surface
- B. Closed surface
- C. Path
- D. Closed path
Explanation
Ampere's law states that the total magnetic field (B) induced around any closed path is equal to the ratio of the total current passing through the closed path to the distance around the path. Therefore, option d is correct.

About Magnetic Flux Density
Magnetic flux density measures the magnetic force acting on a current carrying conductor or moving charge in a magnetic field. Work includes the relations B equals F divided by IL and F equals qvB, the tesla as its SI unit, field direction and the distinction between flux density and magnetic flux.
