Large Magnetic Field Demonstration Plate Chemistry Base-mounted 2-stroke diesel engine model

Base-mounted 2-stroke diesel engine model in aluminum and plastic

5 newtons for measuring small forces during spring-law and tension-force classroom investigations

Three-speed manual transmission with reverse in a clear-plated case

this bottle of coarse 20-mesh iron filings is a staple for classroom magnetism and field-pattern demonstrations

sized for finer-gauge resistance demonstrations and small-scale heating elements where the heavier gauges would over-deliver current

Large Magnetic Field Demonstration Plate Chemistry Base-mounted 2-stroke diesel engine modelSingle large transparent plate filled with iron rod plotting compasses, each one rotating to follow the local field whenever a magnet is placed beneath the plate or alongside it.
