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 length of a hall?
There is no standard size for a hall.
You miss your ssc hall-ticket how you find your hall ticket number?
where is my centre for ssc board 2010, my hall ticket no. a223548
What is the montry hall problem?
Perhaps you mean "Monty Hall" problem. If so, see the related question: What is the Monty Hall Paradox?
Is the hall room compound words?
hall room - not a compound word
How do get hall ticker number of ssc 2012?
how to get hall ticket number of ssc 2012
How do you check whether it is a n type or p type in Hall effect?
if hall voltage is positive then it is p-type & if it is negative then it is n-type semiconductor.
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.
How do you calculate the empty hall resistivity?
Hall resistivity is determined from the polarity of the voltage sum. If the sum is positive, the sample is p-type, if it is negative it is n-type.
Hall effect in semiconductor?
Hall effect
Is Arsenio Hall HIV positive?
Yes Arsenio Hall is HIV positive.
Can insulator be used in hall effect?
no, Hall Effect occurs in semiconductors
When was The Hall Effect - band - created?
The Hall Effect - band - was created in 2004.
Why value of hall coefficient is negative?
The Hall coefficient has the same sign as the charge carrier. The charge carrier in a normal electric current, the electron, is negative, and as a result the Hall coefficient is negative.
Why intrinsic semiconductor has negative halls coefficient?
The difference in the electron and hole mobilities is responsible for the small negative Hall coefficient of intrisic semiconductors. Refs: C.M.Hurd : Hall effect in metals and alloys R.Asokamani :solid state physics Busch& Schade; Solid state Physics
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.
Is there any negative effects to a guild on realm of the mad god?
No actually its more of a positive side, you can ask for hp Pots in the guild hall and can restock for the next big boss you’ll do. There are NO negative things to guilds.
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.
