The direction of magnetic flux can be found by:

Correct answer: B. None of these

  • A. Fleming's right-hand rule
  • B. None of these
  • C. Right hand rule
  • D. Fleming's left-hand rule

Explanation

Magnetic flux describes the number of magnetic field lines passing through a surface. Magnetic flux is the scalar product of magnetic field B and surface area A,ΦB = B ⋅ A = B A cos θAs magnetic flux is a scalar quantity, it only has magnitude and no direction. Hence, its "direction" can not be found by applying any rule.

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.
