Picture a little line of chairs with people sitting in them except the first chair. Now the person in the second chair moves to the first chair. The second chair is empty. Visualize each person in turn moving to the empty chair. The empty chair is now at the other end of the line. This is similar to the way electrons and holes appear in semiconductors. The electrons move and create holes. The holes only appear to move, but the effect is the same. Do the holes move? Effectively, yes, but only by virtue of electron movement.
What else can I help you with?
Can insulator be used in hall effect?
no, Hall Effect occurs in semiconductors
Will hall voltage be identical in semiconductors and conductors?
No, the Hall voltage will not be identical in semiconductors and conductors due to differences in charge carrier concentration and mobility. In conductors, there are typically more free charge carriers, leading to a different Hall voltage response compared to semiconductors, which have fewer charge carriers and can also have both electrons and holes contributing to the Hall effect. Additionally, the type of charge carriers affects the sign and magnitude of the Hall voltage in these materials.
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.
What is defined of Hall effect in metals?
The Hall effect in metals refers to the generation of a voltage difference (the Hall voltage) across a conductor when it is placed in a magnetic field perpendicular to the direction of electric current. This phenomenon occurs due to the Lorentz force acting on charge carriers, causing them to accumulate on one side of the conductor, resulting in a transverse electric field. The Hall effect is used in various applications, including magnetic field sensing and measuring charge carrier density.
How voltage is induced in a permanent magnet pickup coil as the reluctor approaches alignment with the pickup coil.?
The Hall effect.
Hall effect in semiconductor?

When was The Hall Effect - band - created?
The Hall Effect - band - was created in 2004.
What is the difference between ac Hall effect and dc Hall effect?
The AC Hall effect is used to measure the sign and magnitude of an alternating magnetic field, whereas the DC Hall effect is used to measure the sign and magnitude of a steady magnetic field. In AC Hall effect, the magnetic field changes direction periodically, while in DC Hall effect, the magnetic field is constant.
What is Hall effect and what is a Hall effect current transformer?
a current flow close to a magnetic source it influence the sources hall effect is a disturbed signal as a function of speed.
How many holes does it take to fill the Albert Hall?

How many holes does it take to fill albert hall?
Holes don't fill things up, they empty it
Now i am in the kickball hall of fame cause and effect?

How can you find more information about the Hall effect?
The Hall effect was discovered by Edwin Hall, and references the difference in electrical current when exposed to a magnetic field. One can find out more about the Hall effect by consulting a physics textbook or physics teacher or professor.
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
Will hall voltage be identical in semiconductors and conductors?
No, the Hall voltage will not be identical in semiconductors and conductors due to differences in charge carrier concentration and mobility. In conductors, there are typically more free charge carriers, leading to a different Hall voltage response compared to semiconductors, which have fewer charge carriers and can also have both electrons and holes contributing to the Hall effect. Additionally, the type of charge carriers affects the sign and magnitude of the Hall voltage in these materials.
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.
