        It was observed that the magnetic field at one point within the solenoid was fluctuating within a relatively large range. To find out the uncertainty in the readings of the magnetic field sensor, we recorded the magnetic field for a period of 10 s. The mean value of the maximum and minimum value was calculated. The deviation from the mean value then became the uncertainty of the magnetic field strength at that particular point.

Data Collection and Processing:

I → Current flowing through solenoid

B → Magnetic field strength

Raw Data Table showing magnetic field within a solenoid for a particular value of current flowing through it.

Graph of current passing through the solenoid vs magnetic field strength inside the solenoid

Slope of best fit line = -0.406 mT A-1

Maximum slope = -0.289 mT A-1

Minimum slope = -0.497 mT A-1

Thus, slope = -0.406 ±0.117 mT A-1

As we already know, ...
