The diagram shows magnetic field lines. We move from above to below and back.Below shows the graph of variaton of magnetic flux with time. We will measure the flux of
$A$ then $A$
$A$ then $C$
$B$ then $D$
$D$ then $D$
The net magnetic flux through any closed surface is
Write the equation of dipole moment of magnet in the form of electric current.
The distance between the poles of a horse shoe magnet is $0.1\, m$ and its pole strength is $0.01\, amp-m$. The induction of magnetic field at a point midway between the poles will be
Below figures $(1)$ and $(2)$ represent lines of force. Which is correct statement
The magnetic moment of the arrangement shown in the figure is ............. $M$
