- 0 Start here A roadmap: wires, fields and the push in a motor. · 3 min You are here
- 1 The invisible shape around a wire A current makes a magnetic field in rings around its wire. · 8 min
- 2 Drawing the shape Field lines show the direction and strength of a field. · 8 min
- 3 A magnet you can switch A coil makes a strong field. It turns off with the current. · 8 min
- 4 The field pushes back Fleming's left-hand rule gives the direction of the push. · 8 min
- 5 Your house has a circuit A house wiring diagram: live, neutral, earth, a fuse, and parallel branches. · 9 min
- 6 Two kinds of current Direct current keeps one direction. Alternating current reverses at a fixed rate. · 8 min
- 7 Motors A motor turns current into spin. A split ring keeps it turning. · 6 min
- 8 The field of a loop Bend a wire into a loop. Its field runs one way through the loop. · 8 min
- 9 Induction and the generator A moving magnet makes current in a coil. A generator does this all day. · 7 min
- 10 Colours and ratings of house wires Your book gives wire colours. A house often has a 5 A and a 15 A circuit. · 8 min
- 11 Checkpoint: fields, coils and wires Six marked questions on fields, coils, pushes and wires. · 6 min
- 12 The big picture Ten ideas about a current, its field and its machines. · 4 min
- 13 Track quiz The ten rules from the lessons, then fourteen short questions. · 7 min
