Learn how to charge an object by induction using a negatively or positively charged object or an electroscope. See the visualization technique, the electrostatic and electromagnetic induction differences, and the applications of induction charging.
Induction charging is a method used to charge an object without actually touching the object to any other charged object. The process occurs in two steps. The first step involves bringing a charged object near the object to be charged so as to polarize that object.
Learn how to charge objects by contact, induction, or friction with examples and animations. Find out the difference between conductors, insulators, and atoms in electrostatics.
The presence of electric charges on the insulator—and the electric forces they apply to the conduction electrons—creates, or “induces,” the dipole in the conductor. Neutral objects can be attracted to any charged object. The pieces of straw attracted to polished amber are neutral, for example.
The devices that are used to detect the presence of an electric charge on an object are known as an electroscope. So, in the Electroscope Lab, a positively charged object (for example objects such as an aluminium pie plate) is used to charge an electroscope by induction method.
Learn how to charge objects by induction, a process that involves no rubbing, but only the proximity of charged objects. See examples of charging by induction in a metal ball and lightning phenomenon.
Explain what an insulator is. List the differences and similarities between conductors and insulators. Describe the process of charging by induction. In the preceding section, we said that scientists were able to create electric charge only on nonmetallic materials and never on metals.
