Introduction

This JavaScript application appSolenoid models magnetostatic field lines around a solenoid with defined dimensions & current core. The user can modify physical & electrical parameters of the solenoid. Magnetic B-Field lines graphically display a magnetostatic field around current coils in a 10 by 10 centmeter (cm) box.

The user can verify that the B-Field curve plots have curvature based on solenoid dimensions & coil count. Current & core permeability parameters only affect the magnitude & direction along the B-Field line curves. The field lines allude to force direction on a test charge if found @ a location near the solenoid. B-Field intensity may very greatly along each curve. Specifically, a force is generated on a test charge @ right angles to both its velocity & B-Field @ the charge's location.

These B-Fields are calculated using the Lorentz's Force Equation under static conditions. The Electromagnetic (EM) phenomena plotted in this applet was experimentally described by Michael Faraday. Mathematically formulation of B-Fields was made by James Maxwell.
