Question

If Earth's magnetic field lines pass through a Hall probe in the opposite direction, the change in the reading of the voltmeter is:
Options
A Thrice the Earth's magnetic flux density
B Four times the Earth's magnetic flux density
C Five times the Earth's magnetic flux density
D Twice the Earth's magnetic flux density
Correct Answer
Correct Answer

Option D is the correct answer.

Detailed Explanation

Reversing field flips sign of Hall voltage; change = V-(-V) = 2V.

Hint

Reversing field flips sign of Hall voltage; change = V-(-V) = 2V.
