Scientific diagram illustrating different magnet configurations and magnetic fields. Includes a ring magnet, a U-shaped magnet, and interacting disc magnets.

[Neodymium Ring on Drill Shaft - Side View] =================== <- Steel Shaft (spinning) [R] <- Ring Magnet (1" OD, 0.5" ID) / \ <- Magnetic field lines (circling as it spins) | | \ / [S-N] <- Poles: South outer, North inner (or vice versa) [U-Shaped Magnet Holder on Guide Disc - Front View] +-----------------+ <- Disc (aluminum/3D-printed, with wheels) | | | [N] [N] | <- Two Bar Magnets (8 lb pull each, North poles toward door) | | | | <- "Thumbs" sticking out in U-shape | [S] [S] | <- South poles away from door (back of U) | | +-----------------+ ^^^ (Open toward door, creating focused pull field) [Magnetic Interaction - Conceptual Top View, Bit Tilting Right] Door: =================== | [Shaft] | | \ | <- Tilting right (drift) | \ | [Disc A] [Disc B] <- Opposing discs N--[U]--N N--[U]--N <- U-magnets pulling back left | | S S <- Balanced field yanks ring "back left" (Pull stronger on left U due to tilt) See more
