  1. Charging by contact and by induction Gr 9 Science

  2. An electroscope is a device for detecting the presence of an electric charge. • Charging by contact = generating a charge on a neutral object by touching it with a charged object.

  3. Laws of Electric Charges: • = laws that describe how two objects interact electrically with one or both are charged • 1. like charges repel • 2. opposite charges attract • 3. charged and neutral objects attract each other

  4. Electric field = a property of the space around a charged object, where the effect of its charge can be felt by other objects. • Induced charge separation = the movement of electrons in a substance, caused by the electric field of a nearby charged object, without direct contact between the two.

  5. In summary: • 1. an object that is charged by contact has the same type of charge as the charging object. • An electric force between two objects is transmitted by an electric field. • An induced charge separation is the movement of electrons in a substance, caused by the electric field of a nearby charged object.
