Demonstration: a shuttling ping-pong ball serves as a model of ions moving in an electric field.
The aim of this activity is to develop the idea of a magnetic field by engaging pupils in drawing some magnetic field patterns...
Magnetic fields are represented by diagrams which show patterns of magnetic field lines.
A simple way of mapping the rough shape of a magnetic field is to use iron filings. For example, the magnetic field pattern of...
Magnetism is a non-contact force. For example, a magnetic force can be acting on a paper clip when a magnet is nearby but not...
One magnet exerts a force on another. Magnetic field line patterns (see the SPT: Magnetism topic episode 01 for an...
This episode introduces fields, field lines and equipotentials in the context of electric fields. Much of this is revision...
This episode introduces the notion of a "field of force" and how we can diagrammatically represent such a field using field...
