How to choose

For step up and step down transformer work, the Demountable Transformer Kit has a laminated low-loss core and measures 150mm (L) x 170mm (H); add the Demountable Transformer Accessory Set to show step down currents large enough to weld metals or boil water.
The Demonstration Electric Motor runs on 6-8V DC with a removable bar magnet, while the Demonstration Dynamo Model sits on a 230 x 90mm base plate with a 120mm hand-drive pulley and can also run as a motor on 6-8V DC.
The Demonstration Motor AC/DC produces AC and DC current at the same time when its hand wheel is turned, with LED diodes showing the output.
Energy Transfer Kit units share a 165 x 100mm base with 4mm socket terminals: the Spring Unit stores energy in a wound clock spring, the Mounted Solar Cell uses a selenium photo-voltaic cell, and the Line Shaft Unit winds up a weight on a cord.
Choose the Hero Engine to show thermal energy turning into kinetic energy; it needs a bunsen burner, which is not supplied.

Frequently asked questions

What can the Mounted Motor for Solar Cell lift?

Its spindle carries a 16mm diameter pulley and it can raise a mass of at least 4g when powered by the solar cell. It is a small low consumption motor designed to run directly from the solar cell output.

What size is the Demountable Transformer Kit?

The core has a cross-section of 40 x 40mm and the transformer measures 150mm (L) x 170mm (H). The U-shaped metal sheeting closes with two clamps with tightening screws, and different coils can be attached.

How does the Hero Engine work?

Heat from a bunsen burner (not supplied) produces steam jets. By Newton's third law the jets give a backward force to the nozzles, creating a turning movement so the glass apparatus rotates. It models an engine by Hero of Alexandria from about 60 AD.
