What is Hall current in Hall effect?

What is Hall current in Hall effect?

Hall effect, development of a transverse electric field in a solid material when it carries an electric current and is placed in a magnetic field that is perpendicular to the current. This phenomenon was discovered in 1879 by the U.S. physicist Edwin Herbert Hall.

What is current density in Hall effect?

The current density Jx is the charge density nq times the drift velocity vx. In other words. Ix = Jxwt = nqvxwt . (1) The current Ix is caused by the application of an electric field along the length of the conductor.

What is Hall current?

n. Generation of an electric potential perpendicular to both an electric current flowing along a conducting material and an external magnetic field applied at right angles to the current upon application of the magnetic field. [After Edwin Herbert Hall (1855-1938), American physicist.]

How do you find the direction of current in Hall effect?

(b) Positive charges moving to the right (conventional current also to the right) are moved to the side, producing a Hall emf of the opposite sign, –ε. Thus, if the direction of the field and current are known, the sign of the charge carriers can be determined from the Hall effect.

What is Hall voltage and Hall coefficient?

: the quotient of the potential difference per unit width of metal strip in the Hall effect divided by the product of the magnetic intensity and the longitudinal current density.

What is Hall effect current sensor?

A hall effect current sensor allows non-contact detection of direct and alternating currents, using a hall element, a magnet-electric converting element. This minimizes power loss of the target current circuit and has a simple structure with high reliability.

What is the formula for Hall coefficient?

3. What is the formula for the hall coefficient? The hall coefficient formula is RH = Vt/(IB). Here Rh is the Hall coefficient, V is the observed voltage difference, I is current, B is the magnetic field.

What is Hall effect measurement?

The Hall effect is the production of a voltage difference (the Hall voltage) across an electrical conductor that is 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.

How does Hall effect current sensor work?

So, how does a Hall effect sensor work? Using semiconductors (such as silicon), Hall effect sensors work by measuring the changing voltage when the device is placed in a magnetic field. In other words, once a Hall effect sensor detects that it is now in a magnetic field, it is able to sense the position of objects.

What is the Hall effect phenomenon?

What is Hall effect obtaining the Hall coefficient?

An important parameter is the hall coefficient defined as the hall field per unit current density per unit magnetic induction. RH=EH/(JxB)
