SUMMARY
The discussion centers on the relationship between magnetic field strength and electric current, specifically in the context of an experiment involving a compass and a coil of wire. The gradient of the graph represents the proportionality constant (K) in the equation B = KI/R, where B is the magnetic field strength. The experiment utilized a setup with five turns of wire, indicating that the magnetic field strength is directly proportional to the current flowing through the wire. Understanding the experimental setup is crucial for accurately interpreting the results.
