Question
In the figure above, a current flows in a copper wire as shown.
On what side of the copper wire will electrons collect, and what side of the wire will have the highest electrical potential due to the Hall Effect?
Question 3 options:
Electrons will collect to the left, the right side will have the higher potential.
Electrons will collect to the left, the left side will also have the higher potential.
Electrons will collect to the right, the right side will also have the higher potential.
Electrons will collect to the right, the left side will have the higher potential.
aElectrons will collect to the left, the right side will have the higher potential.
bElectrons will collect to the left, the left side will also have the higher potential.
cElectrons will collect to the right, the right side will also have the higher potential.
dElectrons will collect to the right, the left side will have the higher potential.
Explanation / Answer
a) Electrons will collect to the left, the right side will have the higher potential.
From Lorentz force, F = q(v x B), the electrons will be forced to move towards left.
As the electrons move to left the right side will become positive with same charge, so right side will have the higher potential.
