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 inductor’s magnetic field, which … 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 while experiment to show … 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 is the subject of … 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 ‘induced current.’ The result … 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 is called the induced … more
A capacitor is an electronic component made by placing two metal plates close to each other. Capacitors store electrical energy in the form of an electric field. * This simulation only works while pushing with the mouse. * In the … more
Electric voltage(Regions of a positive or negative charge, such as those at the terminals of a battery) force electrons through a conductor. Electrons that have negative charges can be moved around a circuit. Originally, the current was thought to flow … more
This App is a simulation of an electric circuit with a high degree of freedom. You can make the electric circuit you want by connecting batteries, wires, light bulbs, voltmeters, and ammeters. You can adjust the resistor value by clicking … more
This App is a simulation of an electric circuit with a high degree of freedom. You can make the electric circuit you want by connecting batteries, wires, light bulbs, voltmeters, and ammeters. By applying Kirchhoff’s Law, accurate measurements can be … more
Description of the simulation You can compare the two cases with each other. The power plant produced is assumed to be \( 22,000V \times 1A = 22,000W \). You can change the voltage and resistance of the transmission line respectively. … 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 many fields, from small … more
Direction of the Lorentz force 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. More precisely, we … more
