Lorentzs Force
Direction of the Lorentz force Conductors in which current flows in a magnetic field are forced to move. The direction of this force is perpendicular to the current and the magnetic field, respectively. More precisely, we … more

Magnetic Force
Magnetic Force The magnetic force acts between two magnetic objects. Gravity only pulls, but magnetic force also has the force to push, including pulling force. When the different poles of the magnet are close, they pull … more
Oersted’s Experiment
Oersted’s experiment Oersted, a Danish physicist, accidentally discovered the occurrence of a magnetic field around a current-carrying wire. Oersted said that he was surprised to see the compass’s magnetic needle placed next to the wire rotate … more
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 … more
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 … more
