Magnetic Field Produced by an Electric Current A magnetic field is produced not only around a magnet but also around a wire carrying an electric current. This can be observed by watching the needle of a … more
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
What is the difference between a magnet and an electromagnet? Let’s assume there is a small container you can’t see inside. There is a magnetic field around this container that can attract iron. Then, can you … more
CRT TV CRT TV is an image-receiving device that uses cathode rays. It was widely used as a TV receiver until the mid-2000s. However, it had the disadvantage of being large and heavy. Afterward, it gradually … more
You can set the movement of the magnet as you wish. Observe the electromotive force generated depending on the position and speed of the magnet. Electromagnetic induction Moving the magnet around the inductor will change the … more
A cathode ray tube (CRT) is a device that produces cathode rays (a stream of electrons). The inside of the tube is evacuated or filled with a noble gas. When a high voltage is applied to … more
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
Magnetic field created by electric current The magnetic field is the area surrounding a magnet in which the magnetic force exists. The magnetic field is also formed around the conductor through which the current flows. This … more
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 … more
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 … more
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
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 … more
