For which angle between area and magnetic field, the flux is maximum?

Correct answer: A. 0 degree

  • A. 0 degree
  • B. 90 degree
  • C. 45 degree
  • D. 60 degree

Explanation

According to the formula,ΦB = BAcosθWe know that cosθ gives its maximum value (1) when θ = 0°.ΦB = BAcos0°ΦB = BA(+1)ΦB = BAHence, option A is the correct option.

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.
