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 … more
Magnetic Field
Lorentzs Force (Electromagnetic swing)
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 … 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
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 … more
Inductor application circuit
An inductor, also called a coil, choke, or reactor, is a passive two-terminal electrical component that stores electrical energy in a magnetic field when electric current flows through it. Inductors are widely used in alternating current(AC) … more
Magnetic Field around a Circular Wire
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 electromagnetism. The direction of the … more
Magnetic Field around a Wire
You can drag the compass. 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 … more
Magnetic Field around a Bar Magnet
Magnetic field around magnet The space where the magnetic force of the magnet acts is called a ‘magnetic field.’ The direction of the magnetic field is determined in the direction indicated by the N pole of … more
