Does resistance depend on magnetic field?
Does the resistance of a conductor depend upon a magnetic field? – Quora. Yes, it does. Any magnetic field that you apply has an influence on the trajectories of the electrons in the conductor. It leads to the concept called magnetoresistance.
Does the resistance of a conductor depend on magnetic nature?
Resistivity: Resistance depends upon resistivity which is a proportionality constant and depends on the nature of substance and temperature. It is inversely proportional to resistance.
What does the resistance of a conductor depend on?
The resistance of a conductor depends on the cross sectional area of the conductor, the length of the conductor, and its resistivity.
How does conductor affect magnetic field?
For electric fields when a conductor such as an aluminium sheet is placed in the field the field lines get affected due to the conductor. But when a conductor is placed in a magnetic field there will be no change in the magnetic field lines.
Why does resistance increase with magnetic field?
as you increase the magnetic field, an electron gets curved towards edge of the sample. this create a potential difference at opposite edges of the sample, which opposes the cause. since magnetic field increases the potential so the resistance increases as resistance is V/I.
Does increasing the resistance increase the magnetic field strength?
resistance will be R=rho(l+x)/a. it wont increase with a factor of x as in you are not multiplying the additional turns. though the resistance increase but the magnetic field strength increases more.
How does resistance relate to magnetic field?
Applying a magnetic field can also increase the resistance of a material, since the magnetic force on the moving charges will tend to increase the number of collisions between charges. This dependence of resistance on magnetic field is called magnetoresistance.
Which of the following resistance does not depend?
Therefore, out of the options, the resistance of a conductor depends on its length, thickness (i.e. its cross sectional area) and temperature of the conductor. It does not depend on the humidity of the conductor.
How does the magnetic force on the conductor vary with the magnetic field strength?
The strength of magnetic field at a point due to this current carrying conductor is directly proportional tothe current. It means the strength of magnetic field increases with increasein the value of current. The magnetic field produced by a given current in theconductor decreases as the distance from it increases.
What factors influence the magnetic field around a current carrying conductor?
Greater the current in the conductor, stronger will be the magnetic field will be produced. Strength of the magnetic field is inversely proportional to the distance from the wire. Greater the distance from the current carrying conductor, weaker will be the magnetic field.
Does resistance increase magnetic field?
Thus the resistance of the material decreases in a magnetic field.
