About this tool
Magnetic Field Visualization is a free online visual effect. Canvas 2D magnetic field lines visualization with particle motion. Interactive eye-candy rendered live on your screen. It runs entirely in your browser — no download or sign-up needed.
After opening the page, a magnetic field scene will be displayed. There are several magnetic poles on the screen. The magnetic field lines start from the N pole and bend to the S pole. You can drag the magnetic pole to change position and observe the changes in the magnetic field lines.
The whole process is purely front-end animation. The magnetic field lines are drawn based on Canvas, the magnetic field direction at each point is calculated using the principle of magnetic field superposition, and then a curve is drawn along the magnetic field direction.
It is suitable for use as a physics teaching demonstration, electromagnetism popularization, or purely appreciating the symmetry beauty of magnetic field lines. The realization principle is the principle of magnetic field superposition and streamline drawing.
Magnetic field is a visual effect that simulates the distribution of magnetic field lines. It renders the shape and direction of magnetic field lines in real time based on Canvas.
