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 Charging by Induction Concept Builder challenges the learner to use the fundamental concepts of opposites attract and likes repel to explain how objects become charged by induction. There are eight different physical situations to analyze. These are divided into three levels of difficulty.
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.
Electromagnetic Induction Questions. The process of electromagnetic induction generates a voltage or Electromotive Force (EMF) across the electrical conductor due to a changing magnetic field. Electromagnetic induction is generally referred to as induction.
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. The charge flows between two objects and the uncharged conductive material develop a charge with opposite polarity.
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.
Example 1: Consider using a + balloon to charge a neutral conducting sphere by induction. The + balloon forces e-s in the sphere to move from the right side to the left side of the sphere. When touched by the hand. (ground), e-s move from the hand into the sphere. The sphere acquires a - charge.
