# Simulators and Software

## Wheatstone Bridge

This is a virtual lab simulates Wheatstone Bridge. The simulator works correctly only on desktop computers as it requires Mouse Left/Right click and Mouse Wheel. Click the picture below to run simulator.

###### AC Generator

A 3D AC generator simulator. Click the picture below and run the simulator. You can change rotation speed of the loop and analyse relationship between magnetic flux and EMF induced in the loop.  Please do not forget to drag the Slider Button to start simulation.

Magnetic flux through the loop is directly proportional to the area of the loop and magnetic field between two magnets:

$$\Phi = \vec B \cdot \vec{S} = BS \cos \alpha$$

Here $\alpha$ is angle between magnetic field and normal vector of the loop.

$$\alpha = \omega t$$

Here $\omega$ is angular speed, $t$ is time.

According to Faraday’s law of electromagnetic induction, electro motive force (EMF) is:

$$\mathscr{E} = -\frac{d\Phi}{dt}$$

###### Electric Field

An electric field simulator. It is an excellent tool for visualizing electric field and equipotential lines. Visibility of field line and potential surface depends on their magnitude. You can put unlimited number of charges in the field. Also, it can simulate electric field of charged condenser, charged wire and charged dielectric objects. “Electric Filed” have ability to measure field strength and filed potential. Supports MDI, bitmap exporting, and printing. Here are awards for Electric Field.
