SUMMARY
The strength of the induced magnetic field inside an inductor is influenced by both the current flowing through the coil and the inductance of the coil itself. The equation B = μnI indicates that the magnetic field strength (B) is directly proportional to the current (I) and the number of turns per unit length (n). Additionally, the wire gauge affects the maximum current capacity before fusing, which is crucial for coil gun applications. A longer coil can increase the acceleration area but does not necessarily enhance the magnetic field strength if the turns per unit length remain constant.
