SYSTEM NOTE
Polarity changes the shape of the room.
A visual magnetic-field model. Not an engineering simulator.
OBSERVATION CHAMBER / MVP
Magnetic Field Sandbox
Place poles and watch field lines and iron dust swing into alignment.

Prototype
FIELD TABLE
Add or drag N/S poles to watch field lines reconnect, iron-dust particles align, and polarity push against polarity.
First observation
Click empty space to place the selected pole. Drag an existing pole and the field lines will reconnect around it.
N / S / FIELD LINE / IRON DUST
poles 2 / particles 520
OBS-000 / LINES / 00:00
OBSERVATION POINTS
Lines, dust, and interference.
- DIPOLE gives the cleanest read of N/S polarity.
- DUST shows local alignment around poles and between them.
- POLARITY separates field direction from force intensity.
OBSERVATION GUIDE
Touchpoints for Observation
Observe N/S poles bending field lines, aligning iron-dust particles, reversing direction, and interfering with other poles.
- Switch pole presets, use the four lenses, click to add poles, and drag a pole to watch the field reconnect.
- DIPOLE is the cleanest read of polarity.
- DUST makes local alignment easier to see.
- POLARITY separates direction from field strength.

SYSTEM NOTE
field(x,y) is a distance-weighted sum from N and S poles. Field lines follow local direction.
