Define Magnetic field intensity.

Define Magnetic flux

Define electric field intensity and electric potential.Then prove that electric field intensity is negative gradient of electric potential

Define an electric field intensity. Is it a scalar or vector? What is its SI unit?

Derive the expression for the magnetic field intensity due to a bar magnet at any point on its board side-on position. Find the same when the length of the magnetic field intensity due to a bar side-on position. Find the same when the length of the magnet is small.

Define electric field

Define magnetic Dip.

Define Magnetic meridian.
