Nikita gave an information to Rupa as "The magnetic flux passing through a closed area kept inside a magnetic field is zero". How you will agree with it ?

Write the formula for magnetic flux passing through an area A. with an angle theta .

What happens when magnetic flux passing through a coil changes continuously?Where does this process is used ?

How do you denote magnetic flux with a symbol?

How do you find the direction of a magnetic field lines?

A 10 Omega coil of 180 turns and diameter 4 cm is placed in a uniform magnetic field so that the magnetic flux is maximum through the coil's cross-sectional area. When the field is suddenly removed a charge of 360 muC flows through a 618 Omega galvanometer connected to the coil, find the magnetic field.

(A) : If an electron is not deflected while passing through a certain region of space, then only possibility is that there is no magnetic field in this region (R) : Force on an electron moving in a magnetic field is inversely proportional to the magnetic field applied.

How can you verify with experiment."The magnetic field lines are closed loops"?

A beam of the charged particles is passed through a magnetic field. The work clone on the beam by the field is
