Question:

Which of the following is true ?

Options:

When magnetic flux is touching a surface tangentially, the magnetic flux linked with the surface is maximum.

Volt/sec is also an SI unit of magnetic flux.

Lesser the time taken by magnetic field linked with a  surface to change, lesser is the amount of EMF induced.

When conducting wire in N-S direction is dropped freely, the potential difference is maximum.

Correct Answer:

Volt/sec is also an SI unit of magnetic flux.

Explanation:

SI unit of magnetic flux is weber. 

1 weber = \(\frac{1 Joule}{1 Ampere}\) = \(\frac{1 Joule}{1 Coulomb/sec}\) = \(\frac{1 Volt}{1 sec}\)
