Graphing Magnetic Field and Current

Click For Summary
SUMMARY

The discussion centers on a physics lab involving an 18-turn coil where various currents were applied to measure the magnetic field using Data Studio. The magnetic field was recorded in Gauss and converted to Tesla, with measurements taken from 0A to 3A in increments of 0.5A. The results indicated a magnetic field of 1 * 10^-4 Tesla at 0.5A and an increase of 1 * 10^-4 Tesla with each subsequent increment, leading to a non-linear graph despite expectations of linearity. The inconsistency in the graph raises questions about the accuracy of the readings taken during the experiment.

PREREQUISITES
  • Understanding of electromagnetic theory, specifically Ampère's Law

This is not necessarily a homework problem, but it is a lab for physics with which I am struggling. For the lab, I took an 18 turn coil and charged it with various currents. We put a probe at the center of the coil and measured (using Data Studio) the magnetic field. The magnetic field was given in Gauss by Data Studio which I calculated to Tessla (1 Gauss = 1 *10^-4 Tessla). We measured the magnetic field from 0A to 3A increasing in .5A increments. At .5A, the magnetic field was 1 * 10 ^-4 , then at 1A the magnetic field was 3*10^-4. From there the magnetic field increased by 1*10^-4 with each increment.

Later I graphed this and to no surprise, it was not linear. I'm not sure why this happened though, any ideas? I know the graph should be linear.

It looks to me as though you have only 1 reading (from 6) that does not lie on the straight line! ...that is not bad, can you check the readings.
