Can insulator be used in hall effect?
no, Hall Effect occurs in semiconductors
Why alkali metals used in photoelectric effect?
Alkali metals are used in the photoelectric effect because they have low ionization energies, making it easier for photons to eject electrons from their surface. This makes them efficient materials for producing a photoelectric effect. Additionally, alkali metals have a clean surface that allows for reliable and consistent results in experiments.
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 the advantages of the magnetic strip?
Motors and generators are useful devices that use the magnetic effect in a positive way. Several manufacturing processes also use the effect for separating out ferrous metals and detecting flaws in metals. Magnaflux is one example.
Are group 2 elements heavy metals?
Group 2 elements, also known as alkaline earth metals, include beryllium, magnesium, calcium, strontium, barium, and radium. While some of these elements, particularly barium and radium, can be considered heavy metals due to their higher atomic weights and densities, the group as a whole is not typically classified as heavy metals. Generally, heavy metals are defined by their toxicity and density, and many alkaline earth metals do not exhibit the same characteristics as traditional heavy metals like lead or mercury.
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.
Hall effect in semiconductor?
Hall effect
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.
What is the effect of copper and aluminium since they metals?
copper and aluminium are metals since their metals the effect is that their good conductors
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.
What is hot working of metals?
Hot working of metals is defined as a process of forming metals by deformation at temperature above the recrystallization temperature.
Now i am in the kickball hall of fame cause and effect?
an 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
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
