The SI unit of magnetic flux is Weber which is equivalent to:

Correct answer: D. Nm / A

  • A. NA / m
  • B. NmA
  • C. Nm-1A-1
  • D. Nm / A

Explanation

The formula for the magnetic field density (B) is: B=F/IL {where F is the force, I is the current and L is the length of the conductor.} Substitute the SI units into the equation: B=N/Am The magnetic flux is BA therefore: B=N/Am x m2 =NmA-1

About Electromagnetism

Magnetic flux density and magnetic flux describe the strength of a magnetic field and the field passing through a surface. A charged particle moving through a magnetic field experiences a force perpendicular to its velocity and may follow circular or helical motion, depending on the angle between velocity and field.
