Screen too narrow

This Java simulation cannot run on this device because it has a screen that is too narrow. We recommend that, for a better user experience, you run it on a device with a wider screen.

Narrow screen

Although this Java simulation can be run on your device, we recommend that for the better user experience, you run it on a device with a wider screen.

Lorentz force I

When a current flows through a conductor placed in a magnetic field, the conductor is forced to move. The direction of this force is perpendicular to the current and the magnetic field.

DC Motor I

This simulation shows the principle of a DC electric motor. When current is applied to the coil, the direction of the current flowing in the left and right parts of the coil are opposite. Therefore, the direction of the force received by the coil is reversed, and the coil rotates. The direction of the current is changed by the commutator every half turn of the coil, so the coil continues to rotate in the same direction.

DC Motor II

This simulation is another example of the operation of a DC electric motor.

Homopolar electric motor

This simulation shows the principle of a homopolar electric motor. The homopolar motor is a motor that operates using only one polarity of the magnet. The homopolar motor has a very simple structure, is easy to make and is often used in schools to learn the principles of electric motors.
