Static Electricity Simulation | Triboelectric Effect | Electrostatics Simulation | John Travoltage PhET | PhET Simulations

This simulation video explains the concept of static electricity (electrostatics). This Static Electricity simulation demonstrates the generation of static charge on rubbing two bodies. You will learn how the charged body gets neutralized when it comes in contact with a third body having no charge or opposite charge. Hence you will understand the concept of electrostatic discharge (static discharge) with the help of this simulation. 
This is the John Travoltage simulation created by using PhET simulations. The PhET simulation also demonstrates Triboelectric Effect and Triboelectric series (Triboelectricity).

What is Static Charge (Static Electricity)

Static electricity is caused by rubbing two objects and one object supplying electrons to the other. This results an imbalance between positive and negative charges in the object. This causes the body to get charged. This is known as the static charge.

Faraday Law of Electromagnetic Induction | EMI | Lenz Law Simulation | Electromagnetic Induction | PhET Simulations

Here you will understand the conceept of Faraday's Law of Electromagnetic Induction (EMI) and Lenz's Law with the help of a beautiful simulation.
This simulation of electromagnetic induction explains the concept of induced EMF in a coil, when there is a relative motion between the bar magnet and the coil.
The formula of Faraday's law of electromagnetic induction has been made clear experimentally with the help of this simulation.
At the end of this video, it explains the Lenz Law with simulation.
After watching this video you will understand that, negative sign used in the formula of Faraday's law of electromagnetic induction is because of the lenz's law.
This simulation video has been created by using phet simulations (phet Sims).

Faraday's Law of Electromagnetic Induction 

According to the Faraday's Law of Electromagnetic Induction, if a conductor is placed in a varying magnetic field then emf (electromotive force) is induced in the conductor. If the conductor circuit is closed then current is induced which is called as induced current. This induced emf is equal to the rate of change of flux linkage with the coil.

Lenz's Law definition

Lenz's law states that the direction of the induced current produced in this phenomenon is such that the magnetic field produced by this induced current opposes the magnetic field that produced it.
