Write the equation of magnetic field obtain in the core of solenoid in the form of `overset(to) (H) and overset(to) (M)`.

Write equation of magnetic field at inside point will of very long solenoid.

Derive equation of magnetic field inside a long straight solenoid.

Write the equation of magnetic field on the axis of current carrying finite solenoid.

Write the equation of dipole moment of magnet in the form of electric current.

What is magnetic field outside solenoid ?

Suppose we want to verify the analogy between electrostatic and magnetostatic by an explicit experiment. Consider the motion of (i) electric dipole overset(to)(p) in an electrostatic field overset(to) (E ) and (ii) magnetic dipole overset(to)(M) in a magnetic field overset(to)(B) . Write down a set of conditions on overset(to)(E) , overset(to)(B), overset(to)(M) so that the two motions are verified to be identical. (Assume identical initial conditions.)

Inside the solenoid, magnetic field lines in the middle part are ______

Verify the Gauss's law for magnetic field of a point dipole of dipole moment overset(to)( M) at the origin for the surface which is a sphere of radius R.

Write the equation of torque acting on bar magnet placed in uniform magnetic field.
