physical significance electric dipole

Electric Dipole - It is a pair of point charges with equal magnitude and opposite in sign separated by a distance. Many physical systems from molecules to TV antenna can be described as electric dipoles. A water molecule is an example of an ele..

Potential at a point due to a dipole along the axis - The potential at point P is the algebraic sum of the potentials due to -q and +q charges. Hence Potential at point P due to the dipole along the equatorial line will be zero as P is equidistant from the two charge..

Just as the electric field is described as force per unit charge, electric potential at a point can be described as electrical potential energy per unit charge. This concept is useful in calculations involving energies of charged particles. Not only that, as force is ..

Dipole in a Uniform External Field - An electric field is said to be uniform if the electric field strength at every point in the field is the sa..

When an electric current flows in a closed loop of wire, placed in a uniform magnetic field, the magnetic forces produce a torque which tends to rotate the loop so that area of the loop is perpendicular to the direction of the magnetic fiel..

. Electric dipole is a pair of equal and opposite point charges separated by a small distance. In a uniform electric field, a dipole experiences a torque, and net force becomes zero. Various properties of Electric field lines: (a) lines are continuo..

On comparing the two-field pattern, the current carrying solenoid from outside resembles a bar magnet. Inside the solenoid there is a strong magnetic field, which can magnetise a specimen. Solenoid is hollow from inside whereas the bar magnet is solid. Here we note the close similarity between the..
