Magnetism.
- Videocassette (VHS)(14 min.) : sd., col., 1/2 in.
Part One of a two-part film on magnetism which looks at Faraday's idea of a magnetic field or how the presence of the magnet makes a difference to the space it surrounds by giving it magnetic effects, and how you can map out the direction of the magnetic force by the lines along which a compass sets itself by means of iron filings.
Magnetism--Study and teaching.
