What else can I help you with?
Can insulator be used in hall effect?
no, Hall Effect occurs in semiconductors
Hall effect can be used to measure?
Hall effect can be used to measure the strength of a magnetic field. When a current passes through a conductor in a magnetic field, a Hall voltage is generated perpendicular to both the current and the magnetic field. By measuring this Hall voltage, the strength of the magnetic field can be calculated.
Why hall voltage increases with increase in magnetic field?
Since eEH= e(V X B) As magnetic field increases the lorentz force acting on the carriers increases which in turn increases the hall field associated with the carriers and hence hall voltage increases as magnetic field is increased.
How voltage is induced in a permanent magnet pickup coil as the reluctor approaches alignment with the pickup coil.?
The Hall effect.
What is Lloyd Halls mothers name?
Lloyd Hall's mother's name was Amanda Jackson Hall.
Can insulator be used in hall effect?
no, Hall Effect occurs in semiconductors
What do you understand by negative and positive hall effect?
The Hall effect refers to the generation of a voltage difference across an electrical conductor when it is exposed to a magnetic field perpendicular to the current flow. The positive Hall effect occurs in materials where the charge carriers are positive holes (like in p-type semiconductors), resulting in a voltage that indicates the direction of the magnetic field. In contrast, the negative Hall effect occurs in materials with negative charge carriers (like electrons in n-type semiconductors), producing a voltage that reflects the opposite direction of the magnetic field. This phenomenon helps in determining the type of charge carriers in a material and is widely used in sensors and electronic devices.
What is the difference between hall-effect in metals and semiconductor?
because we have hall cofficient =1/ne. where the n=no of electron ,e=charge of electron. we know that "n "in metal is very large. so that R=HALL COFFICIENT" is very small FOR it .so we can not find sufficient result for hall cofficient so we use semi conductor which gives non zero hall cofficient.
Which shows a stronger hall effect metallic conductor or semiconductor?
semiconductors
What is hall effect hall voltage?
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 a magnetic field perpendicular to the current. It was discovered by Edwin Hall in 1879
When was National Band Association Hall of Fame of Distinguished Band Conductors created?
National Band Association Hall of Fame of Distinguished Band Conductors was created in 1979.
Hall effect in electronics and communication?
When a current carrying conductor placed in magnetic field than a voltage across the surface is arise this voltage is known as hall voltage and this phenomenon is know as hall effect. It is useful for consider whether the applied material is PNP or NPN
What is the hall effect voltage in intrinsic silicon?
zero

When a current passes through a conductor in a magnetic field, a Hall voltage is generated perpendicular to both the current and the magnetic field.

What is Hall Current Sensor?
A hall current sensor produces voltage by means of the "hall effect". It is used in automobile applications such as wheel speed sensors, tachometers, speedometers and ignition.
Why hall voltage increases with increase in magnetic field?
Since eEH= e(V X B) As magnetic field increases the lorentz force acting on the carriers increases which in turn increases the hall field associated with the carriers and hence hall voltage increases as magnetic field is increased.
How does a hall effect switch works?
A Hall effect switch operates based on the Hall effect, which occurs when a magnetic field is applied perpendicular to the flow of current in a conductor. When a magnetic field is present, it induces a voltage (Hall voltage) across the conductor, which can be detected by a sensor. This change in voltage signals the switch to either open or close a circuit, allowing it to control devices like motors or lights without any physical contact. Hall effect switches are commonly used in applications where reliable, non-contact switching is desired.
