Ampere's law is ∫B.dl =

Correct answer: C. µI

  • A. µI2
  • B. µ/I
  • C. µI
  • D. Iµ2

Explanation

Ampere's law states that the sum of the dot product of the tangential components of magnetic induction (B) and, the respective length of individual elements (dl) of a closed path around a conductor, is equal to the product of the current enclosed (I) and u (magnetic permeability).

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.
