Magnetic flux is maximum when the angle between the magnetic field and the normal to the plane of finite area is
Correct answer: A. Zero degree
- A. Zero degree
- B. 90 degree
- C. 60 degree
- D. 30 degree
Explanation
Magnetic flux (Φ) through a finite area is given by:Φ = B × A × cos(θ)where:B = magnetic field strengthA = area of the planeθ = angle between the magnetic field and the normal to the planeWhen θ = 0°, the magnetic field is parallel to the normal, and cos(0°) = 1. This means the magnetic flux is maximum, since the field lines pass through the area at a 90° angle, resulting in the maximum amount of flux.

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.
