OBSERVATION CHAMBER / MVP

Magnetic Field Sandbox

Place poles and watch field lines and iron dust swing into alignment.

magnetic Operational

FIELD TABLE

Add or drag N/S poles to watch field lines reconnect, iron-dust particles align, and polarity push against polarity.
OBSERVING
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

SYSTEM NOTE

Polarity changes the shape of the room.

A visual magnetic-field model. Not an engineering simulator.

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.

This is a visual magnetic-field model, not an engineering simulator.

Runs inside the browser with no upload and no registration.

SYSTEM NOTE

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

OBSERVATION POLICY

This observation LAB runs in your browser. It does not upload images, pointer traces, or input.

Continue observation through connected systems.
