self inductance and mutual inductance we are aware that whenever an electric current flows through a conductor, a magnetic field surrounding it is produced. a varying current results in a varying magnetic field. due to this, the magnetic flux varies and an electromotive force is induced in the ...
Is magnetism a chemical property? What is the electromagnetic force? What is an induced magnetic field? Is magnetism a physical property? What is the magnetic field of a bar magnet? What is mu in Faraday's law? What creates a magnetic force?
In summary, the conversation is discussing the calculation of the emf induced in a tightly wound coil at the center of a solenoid with specific dimensions and a varying current. The formula for calculating the magnetic field of the solenoid is mentioned, as well as the use of the solenoid's...
Inductance property is found in most of the electric coils, where an induced emf is generated in a coil when there is a change in flux. In simple terms, this is known as the induction effect. However, talking about the measure of this property, various units are used. We will look at...
voltage v (t) across an inductor with inductance L and the time-varying current i (t) passing through it is described by the differential equation: v(t) = L \frac{di(t)}{dt} When there is a sinusoidal alternating current (AC) through an inductor, a sinusoidal voltage is induced. htt...
The law says that the magnetic field induced by the current, when integrated along the closed loop C is proportional to the current enclosed by the loop. Maxwell understood that the Ampere's Law does not apply to all situations and saw the need for another term - called the displacement ...
When formers are used, they will be chosen from a material that does not conduct current - if it did conduct current then currents would be induced in the former this would destroy the action of the inductor. Accordingly insulating material are often chosen: plastic, ceramic and the like. ...
Magnetic permeability is a property that describes how easily any material is influenced by an induced magnetic field. It is sometimes known as electromagnetism. This measure helps us know a material's ability to allow the passage of magnetic field lines through it. When a material is placed in...
