Reluctance is the opposition offered by a magnetic circuit to the formation of magnetic flux. It is equivalent to resistance in an electric circuit.
Reluctance is the ratio of a magnetic circuit's magnetomotive force (measured in amperes) to its magnetic flux(measured in webers, pronounced 'vay-bers'). So, reluctance is measured in amperes per weber (which is often 'spoken' as 'ampere-turns per weber'). This is equivalent, in an electric circuit, to the ratio: electomotive force to electric current.
What else can I help you with?
What is magnetic balance test of transformer?
The Magnetic Balance test is conducted on Transformers to identify inter turn faults and magnetic imbalance.
What happens to the magnetic field if the current in the wire increases?
If the current in the wire increases, the magnetic field also increases.
How does the magnetic circuit concept aid in the design of transformer and machine cores?
The magnetic circuit concept simplifies the analysis of magnetic fields in transformers and machine cores by allowing engineers to model the magnetic path as a series of magnetic components, similar to an electrical circuit. This approach helps in calculating parameters such as magnetic flux, reluctance, and magnetomotive force, enabling the optimization of core materials and geometries for efficiency. By understanding the magnetic circuit, designers can minimize losses, enhance performance, and ensure that the core can handle the required magnetic flux without saturation. Ultimately, this leads to improved reliability and efficiency in electrical devices.
Why is air gap is necessary in particle magnetic circuits?
Mainly air gap is necessary in magnetic circuit for two necessary reasons: 1. to prevent saturation 2. to allow an object to move in the magnetic field
What is a shading coil?
A shading coil induces currents to create an additional electrical phase. The coil pauses slightly to control magnetic flux. Delaying magnetic flux allows for a secondary rotating magnetic field to build.
