In polar dielectrics , tiny electric dipoles are randomly oriented

Assertion: When a dielectric material is kept inside some external electric field then the net electric field intensity inside the volume of dielectric is always less than external electric field intensity. Reason: In a normal state, polar molecules of dielectric material are randomly oriented and their net electric field remains zero. If we apply electric field on a dielectric material then the polar molecules experience torque and gets aligned along its direction.

An electric dipole placed in an electric field experiences a torque. When a dipole is placed in a uniform electric field the torque acting on it is found to be 0.707 times the maximum torque. Calculate the angle between the Intensity of electric fied and electric dipole moment and draw the orientation of the dipole in the electric field.

Assertion : In the absence of an external electrical field, the dipole moment per unit volume of a polar dielectric is zero. Reason : The dipoles of a polar dielectric are randomly oriented.

Assertion: In the absence of an external electric field, the dipole moment per unit volume of a polar dielectric is zero. Reason : The dipoles of a polar dielectric are randomly oriented.

Define electric dipole and electric dipole moment.

Assertion: In the absence of an external electric field, the dipole moment per unit volume of a polar dicletric is zero. Reason : The dipoles of a polar diclectric are randomaly oriented.

Assertion: In the absence of an external electric field, the dipole moment per unit volume of a polar dicletric is zero. Reason : The dipoles of a polar diclectric are randomaly oriented.

How a non polar dielectric develops a net dipole moment when placed in electric field?

A: In a diamagnetic substance each atom has a non-zero dipole moment but due to thermal agitation the individual dipoles ramein randomly oriented and, therefore, the net dipole moment in any finite volume of the substance remains zero. R: On increasing the temperature the magnetism inside a perament magent increases.
