Electromagnetism Simulation

AC Power Generator

AC Power Generator

Electromagnetic induction Moving a magnet around a coil changes the magnetic field inside the coil, which causes current to flow through the coil. This phenomenon is called ‘electromagnetic induction’; the current flowing through the coil is ‘induced current.’ The result...

Faraday's Law of Electromagnetic Induction

Faraday’s Law of Electromagnetic Induction

Electromagnetic induction Moving the magnet around the inductor will change the inductor’s magnetic field, which will cause the current to flow through the inductor. This phenomenon is called electromagnetic induction. The current flowing in the inductor is called the induced...

Speaker

Microphone and Speaker

The simulation works by recognizing the surrounding sounds. Please turn off the silent mode on your mobile device for microphone detection. In the case of PC, please grant permission to use the microphone. Voice data is not stored on servers,...

DC Motor Simulation

DC Motor 2

Motor An electric motor is a device that converts electrical energy into mechanical energy by utilizing the force received by a conductor through which a current flows in a magnetic field. Electric motors are used in many fields, from small...

Homopolar Motor

Homopolar Motor

Assuming that the current flowing in the wire is in the X-direction, the magnetic field is in the Y direction. Then, what direction is the electromagnetic force? ‘Homopolar motor’ refers to a motor operated by using only one polarity of...

Electric Transformer

Electric Transformer

* We assume an ideal transformer where the excitation current is “0”. Electric transformer A transformer is a device for simply changing the voltage of an alternating voltage (AC). Transformers make it easy to change the voltage of an AC...
