Electricity & magnetism
A rotating magnet changes the direction of nearby magnetic needles. The needle array makes the changing magnetic field visible.
RELATED PHYSICAL DEMONSTRATION
Both show an array of magnetic needles responding to a movable magnet. The source uses a vertical transparent panel on a green cabinet; the catalogue uses a horizontal array of blue circular needle housings. The activity is related, the configuration is different.
Video & text guideThis company footage demonstrates the same activity in a different physical configuration. It is not footage of the catalogue rendering shown above.
THE ACTIVITY & MECHANISM
A rotating magnet changes the direction of nearby magnetic needles. The needle array makes the changing magnetic field visible. Each needle responds to the field at its own location, producing an array of directions rather than showing a single force arrow.
Rotate the magnet.
Observe the nearby needles.
Compare their directions at different positions.
