Let uncharged conductor B mounted on the insulated stand is placed near +vely charged conductor Amounted on the insulated stand without touching.
Electrons which are equal in number of protons in uncharged B, are attracted towards +vely charged A. Hence end E is charged negatively called BOUND CHARGE and protons remain at end F of B and is positively charged called FREE charge: This induced charge remains on B so long as body A remains near B.
