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.
The basic process of generating currents with magnetic fields is called induction; this process is also called magnetic induction to distinguish it from charging by induction, which uses the electrostatic Coulomb force.
Induction charging is a charging method that charges an object without actually touching the object to any other charged object. The charging by induction process is where the charged particle is held near an uncharged conductive material that is grounded on a neutrally charged material.
Induction Experiments. (Faraday / Henry) - An induced current (and emf) is generated when: (a) we move a magnet around a coil, (b) move a second coil toward/away another coil, (c) change the current in the second coil by opening/closing a switch. -Magnetically induced emfs are always the result of the action of non-electrostatic forces.
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.
Electrical conductors moving through a steady magnetic field, or stationary conductors within a changing magnetic field, will have circular currents induced within them by induction, called eddy currents. Eddy currents flow in closed loops in planes perpendicular to the magnetic field.
We have another way of charging the objects, which is called charging by induction. Therefore, we can charge the objects through rubbing process, and also through induction. Let’s consider charging by induction, through an example.
