The answer is because it puts out 2 pulses for every rotation.
So, in order fix this problem we should change the gain in oscilloscope from
+60.000,000 to +30.000,000
Now we will be getting the exact value as it is in the tachometer.
Question: Why does the oscilloscope double almost the exact value of rotational speed measured by Tachometer?
Rotational speed from Tachometer = 1930 [RPM]
Frequency of 1 period = 64.3 [Hz] which means 3857.91 [RPM]
The output waveform of hall-effect sensor is attached.

I would prefer not to share it here because the correct answer doesn't match with my solution. Let's say you solving the problem, Can you tell what you're going to do to solve for Vth?
Problem 52:
A solenoid is 40 cm long, has a diameter of 3.0 cm, and is wound with 500 turns. If the current through the windings is 4.0 A, what is the magnetic field at a point on the axis of the solenoid that is (a) at the center of the solenoid, (b) 10.0 cm from one end of the solenoid, and...
