definition electrostatic induction

Answer:
Explanation:
Electrostatic induction is a method to create or generate static electricity in a material by bringing an electrically charged object near it. This causes the electrical charges to be redistributed in the material, resulting in one side having an excess of either positive (+) or negative (−) charges.
This phenomenon is most effective when the objects are conducting materials, such as a metals. The only drawback is that once the electrically charged object is removed, the conductor loses its charge. This can be solved by temporarily grounding the conductor.
Certain non-conducting materials can also be given a static electric charge by electrostatic induction. In these cases, it is caused by polarization of their molecules.
First of all electrostatic induction is a process of charging. For example, let's say that we brought two conductors separated at some distance, also one conductor (say A) is charged while other (say B) us uncharged or neutral. Now as we bring the conductor A near B, B gets induced due to the electric field produced by A. Also the charge on be is the opposite of the charge on A. This process of charging is know as electrostatic induction. It's practical example can be seen in our daily life, like after combing your hair if you bring the comb near some piece of paper, the papers get partially attracted to comb. This is because, while combing, the comb draws some electrons from your head and gets negatively charged and when we brought it near piece of paper, it induces the paper to generate positive charge and hence it can attract the papers. I am sure now you can think of some more examples by your own.
If you want to see these experiments you can refer to some lectures of Walter lewin that is 8.01 and 8.02, which are available on YouTube.

Answer:
Electrostatic induction, modification in the distribution of electric charge on one material under the influence of nearby objects that have electric charge. Thus, because of the electric force between charged particles that constitute materials, a negatively charged object brought near an electrically neutral object induces a positive charge on the near side and a negative charge on the far side of the neutral object. The neutral object, furthermore, may sometimes become charged positively by induction, if its negative part is grounded momentarily to permit the negative charge to escape. Electrostatic induction occurs whenever any object is placed in an electric field. See also electric polarization.
