Asked in UHS MDCAT 2009 2009Moderate

The value of permeability of free space μo is:

Correct answer: A. 4π x 10-7 WbA-1m-1

  • A. 4π x 10-7 WbA-1m-1
  • B. 4π x 102 WbA-2m-2
  • C. 4π x 10-7 WbA-2m-1
  • D. 4π x 102 WbA-1m-2

Explanation

Explanation: The value of permeability of free space μo is 4π × 10-7 WbA-1m-1. It is a physical constant that relates the strength of a magnetic field to the current producing it, and it is also used to define the unit of magnetic flux density, the Tesla.

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.
