Bar Magnet Field Line Simulator

Explore the interaction between Earth's magnetic field and a bar magnet using this interactive JavaScript HTML5 applet simulation model. Learn about magnetic fields and their effects in a dynamic and engaging way. Control the orientation and strength of the bar magnet, observe how it aligns with Earth's magnetic field, and discover the principles of magnetism through hands-on exploration.

Controls:

ComboBox: Easily set the four directions of the bar magnet or find the rotation symbol and drag to control the amount of rotation.
Checkboxes: Control whether the compass or Earth appears.

Question

Experience the dynamic interaction between the bar magnet and Earth's magnetic field as you rotate the magnet. Take note of the position of Geographical North as you make adjustments. What observations did you make?
