The Magnetic Field JavaScript model shows the field of a bar magnet, a coil and Earth and has a movable compass that reports the magnetic field values. The model is built by placing a group of magnetic dipoles along the bar magnet. Why is it reasonable to model a magnet using multiple dipoles?

The Magnetic Field JavaScript model was developed using version 5 of the Easy Java Simulations (EJS 5) modeling tool. Although EJS is a Java program, EJS 5 creates stand-alone JavaScript programs that run in almost any browser.
