Define hall coefficient and its importance in physics
Answers
Answer:
Hey mate ✌️✌️
Explanation:
The Hall effect is the production of a voltage difference (the Hall voltage) across an electrical conductor, transverse to an electric current in the conductor and to an applied magnetic field perpendicular to the current. It was discovered by Edwin Hall in 1879.[1] For clarity, the original effect is sometimes called the ordinary Hall effect to distinguish it from other "Hall effects" which have different physical mechanisms.
The Hall coefficient is defined as the ratio of the induced electric field to the product of the current density and the applied magnetic field. It is a characteristic of the material from which the conductor is made, since its value depends on the type, number, and properties of the charge carriers that constitute the current.
Hall Coefficient is defined below:
- The Hall effect is a phenomenon whereby a transverse electric field develops in a solid material when the substance is exposed to a magnetic field that is perpendicular to the current.
- In 1879, Edwin Herbert Hall made the discovery of the Hall effect. Let's explore the Hall effect in greater detail in the next paragraphs.
- According to the Hall effect's basic tenets, a voltage can be measured at a right angle to the current route when a semiconductor or conductor carrying current is subjected to a perpendicular magnetic field.
- The Hall effect is the name given to this phenomenon of measuring voltage.
It's Important in physics are mentioned below:
Following situations involve the application of the Hall effect principle:
- Sensing devices for magnetic fields
- Hall effect tong testers are utilised to measure direct current.
- It is employed for measuring phase angles.
- Nearby detectors Hall effect Sensors and probes Linear or angular displacement transducers for determining wheel speed
- helping the anti-lock brake system accordingly
Hence, this is the Hall Coefficient and it's important in Physics.
