Answers
Explanation:
potential difference, known as the Hall voltage will be generated between both sides of the plate which can be measured using a meter. The Hall voltage represented as VH is given by the formula: V_H=\frac{IB}{qnd}
magnetic field
the portion of space near a magnetic body
or a current-carrying body in which the magnetic forces due to the body or current can be detected.
Ampere's Law Formula. Ampere's law allows us to calculate magnetic fields from the relation between the electric currents that generate this magnetic fields. It states that for a closed path the sum over elements of the component of the magnetic field is equal to electric current multiplied by the empty's permeability.
Faraday's law of induction is a basic law of electromagnetism predicting how a magnetic field will interact with an electric circuit to produce an electromotive force —a phenomenon known as electromagnetic induction.

•) what is magnetic field? and its formila?
an area around a magnet or materials that behave like a magnet, where there is a force that will attract some metals towards it
Formula
F=q v B \sin \theta
mean by formula
F = magnetic force
q = charge of moving particle
v = particle velocity
B = magnetic field
\theta = angle between velocity and magnetic field vectors
•) what is ampere's law? and its formula?
Ampere's Law states that for any closed loop path, the sum of the length elements times the magnetic field in the direction of the length element is equal to the permeability times the electric current enclosed in the loop. ...
Formula
l}=\mu_{o} I
mean by formula
l}= line integral of B around a closed path
\mu_{o} = permeability of free space
I = current
•) what is farady's law? and its formula?
Faraday's law of induction is a basic law of electromagnetism predicting how a magnetic field will interact with an electric circuit to produce an electromotive force —a phenomenon known as electromagnetic induction.
Formula
E =-N \frac{\Delta \Phi}{\Delta t}
E = induced voltage
N = number of loops
{\Delta \Phi} = change in magnetic flux
{\Delta t} = change in time
