Question

What is the flux when the magnetic field is at an angle \[\theta\] to the area vector?

विकल्प

• \[\Phi_B=BA\sin\theta\]

• \[\Phi_B=BA\cos\theta\]

• \[\Phi_B=BA\]

• \[\Phi_B=0\]

Answer 1

The flux depends on the angle between the magnetic field and area vector. The dependence is given by \[\cos\theta\].
