# Fuels, the Sun and saving energy, sentence 11

<!-- .ven lang=en -->
A bike dynamo spins a magnet in a coil and turns the movement of the wheel into electricity for the lamp; the faster the wheel spins, the more it makes.

<!-- .vintro -->
**Who acts:** bike dynamo, wheel · **What happens:** spin, turn, make, move · **To what, where:** magnet, coil, movement, electricity, wheel

<!-- .vabout -->
This is a sentence of the lesson «Fuels, the Sun and saving energy» of the physics course of Mova's primary school. The page gives its syntax tree — a dependency tree in the style of Universal Dependencies — and its pragmatics clause by clause: who acts (bike dynamo, wheel), what happens, when and where, as Mova's frames read it from the tree.

**The tree:** Mova annot: Rust (en) → Haiku 5.5 (medium, Batches API) patches; gates UD 2.18; agreed by treeagree rules (Stanza, Trankit, spaCy trf): R2-punct-next ×1, R5-strong ×1. **The frames** are read from the tree by Mova's frames reader (`prag`) when this page is built, the lesson read in order, so a pronoun may be resolved from an earlier sentence.
