Demonstration Transformer Set, Advanced
The classic demonstration transformer apparatus is added with some additional safety features. Rather than the traditional mains (220-230V AC) coil we have designed a dedicated Demonstration Transformer Power Supply with fixed (25V AC) voltage and high current output to which 100-turn or 150-turn mains coil substitutes connect. The advantage is that no lethal mains voltage is involved, instead the voltages to these mains coil replacements is 25V AC and so safe. Additional AC and DC outputs are provided up to 4V for other experiments.

Demonstration Transformer Induction Accessory Kit
Includes:
- Copper Coil – With screw clamps to hold a nail for the nail melting demonstration.
- Nails – Steel flat-headed nails 65 x 3 mm or 2½ x 1/8 inch, some with a central groove making the nail thinner at that point.
- Solid and Split Aluminium Rings-Two solid and one split for the ring-launching demonstration.
- Solder Trough – Effectively a single turn coil in the form of a circular trough. Approximately 300 mm of solder is formed into a 50 mm dia meter circle to lie in the trough.
