Using Experiment and Computer Modeling to Determine the Off-Axis Magnetic Field of a Solenoid
Lietor-Santos, Juan Jose
Physics Teacher, v52 n9 p561-563 Dec 2014
The study of the ideal solenoid is a common topic among introductory-based physics textbooks and a typical current arrangement in laboratory hands-on experiences where the magnetic field inside a solenoid is determined at different currents and at different distances from its center using a magnetic probe. It additionally provides a very simple scenario in which Ampère's law can easily be applied by using a rectangular area that is pierced by a certain number of turns of the solenoid. The integration path is laid out in such a way so that part of it lies outside the solenoid; in so doing, the familiar result B[subscript solenoid] = µ N/L I is obtained, where µ is the magnetic permeability, N is the number of turns of the solenoid, L is the length, and I is the current.
