A charge moving through a magnetic field is pushed sideways — and because the force is always perpendicular to the velocity, it changes direction without ever changing speed. The result is a perfect circle. This is the real knowscape from knowhere, not a picture of one. Drag it. Watch what actually changes.
A field is a region that pushes. Electric fields push charges along themselves and trade voltage for speed; magnetic fields only ever push sideways, turning paths into circles. Watch the trajectory: a parabola says electric, a circle says magnetic — same charge, two signatures.
You sprint the straight, nothing turning you, speed locked in.
A force pulls you sideways, always inward, never speeding you up.
That constant inward tug keeps you circling the same loop.
knowhere maps every concept to what it rests on and what rests on it — 0 underneath this one, 1 built on top. Each one says why, in a sentence, not as an arrow on a diagram.
Each one is its own knowscape in the app — built for how a particular student takes things in, not one explanation handed to everybody.
Every HSC and VCE concept in knowhere is built like this one — mapped to your curriculum, never capped by it. Free for a week. No card tricks, no lecture.
Free for a week, then $49 once — the 2026 exam pass ends itself after the last exam. 0 days of the pass left.
Free for a week, then a plan you can stop any time.
