Field lines

Skills: Know

Statement

Outside a magnet, the magnetic field lines go...

  1. From the north pole to the south pole
  2. From the south pole to the north pole
  3. In circles around the magnet
  4. Nowhere: they stay inside
2 hints from Bastaya available in the lab
Solution

Convention: field lines leave from the north, enter at the south, and close inside the magnet.

Circuit diagram CEI 60617

How does it work?

Each big hole is a circuit node: you push one leg of a component into it. The 4 small holes around it are connected to it: chips and leads plug in there.

  1. Place a component Drag it from the palette: it snaps onto the grid. R rotates it.
  2. Bridge neighbouring holes Pick the jumper chip (or C) and drag on the board: bridged holes become a single node.
  3. Draw a lead For long links and the power supply: from one big hole to another, or to a terminal.
  4. Close the loop The circuit is solved live (Ohm, Kirchhoff) and the diagram follows.
