What happens to the flux if applied magnetic field is doubled on the same surface?
Correct answer: B. Becomes twice
- A. Becomes half
- B. Becomes twice
- C. Becomes infinite
- D. Becomes 4 times
Explanation
The magnetic flux through a closed loop is directly proportional to the magnetic field passing through the loop. Therefore, if the magnetic field doubles, the magnetic flux through the loop will also double, provided that the loop remains in the same position and orientation with respect to the magnetic field.The relationship between magnetic flux and the magnetic field is described by Faraday's law of electromagnetic induction, which states that the induced electromotive force (EMF) in a closed loop is proportional to the rate of change of magnetic flux passing through the loop

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.
