can someone in detail explain to me why can't a dielectric attract charges?
sophiecentaur said:The induced polarisation in a dielectric can cause attraction. Dust particles are attracted to a charged rod even when they have no net charge.
So the OP is not strictly accurate except in a uniform field.
I know that they can attract but just wanted to know in an instance where charges wouldn't attract. Thanks for the replysTJGilb said:This is also true. Any induced charge will create it's own electric field as I said, which can interact with charges the way any other electric field would.
A dielectric charge is an insulating material that does not conduct electricity. It can become polarized when placed in an electric field, meaning the positive and negative charges within the material are separated.
Dielectric charges do not attract because they do not have freely moving charges, like conductive materials do. The separation of positive and negative charges within a dielectric material results in a net neutral charge, which does not create an attractive force between objects.
Dielectric charges can change the strength and direction of electric fields. When placed in an electric field, the polarized charges within the dielectric material can weaken or disrupt the field, depending on the orientation of the material.
Yes, dielectric charges can be used to store electricity. Capacitors, which are devices used to store electrical energy, often use dielectric materials between their two plates. The polarized charges within the dielectric material allow for the storage of electrical energy.
No, not all insulating materials are considered dielectric charges. Dielectric materials have a specific property known as permittivity, which measures their ability to become polarized in an electric field. Materials with a high permittivity, such as glass or plastic, are considered dielectric charges, while materials with a low permittivity, like rubber, are not.
