We have discussed the electric field and potential. Electric potential is a scalar quantity but electric field is a vector quantity. How ar...

We have discussed the potential due to point charge, electric dipole, etc. Now let us go through the equipotential surface and its properti...

You have seen that materials like iron, steel etc are strongly attracted by external magnetic field, while wood, aluminium etc. do not show...

Why do we define electric potential?        We have defined potential energy of a test charge q in terms of the work done on the charge q. ...

        To get a clear idea about electrostatic potential energy, consider the field E due to a charge Q placed at the origin. Now, imagine...

      In class XI, the notion of potential energy was introduced. When a body is taken from a potential energy was introduced. When a body ...

You have seen that a freely suspended or pivoted magnet comes to rest along the north-south direction. Experiments have shown that the eart...
