Thermocouple, Double, Mounted

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.

This heavy duty demountable transformer can be used for the study of transformer theory and many other alternating current phenomena. This kit consists of:

• A magnetic circuit made of highly permeable U shape metal sheet, which can be closed using two clamps with tightening screws.
• Section: 40 x 40 mm with 150 mm length and 170 mm height.
• One coil of 6000 turns with maximum current of 0.2 ampere. Intermediary coil of 2000 turns output.
• One coil of 600 turns with maximum current of 2.5 ampere, which is mainly used to create the primary of transformer.
• One coil of 1200 turns, with maximum current of 1.25 ampere, fitted with intermediary 400 and 800 turns’ outputs.
• One coil of 72 turns, with maximum current of 12 ampere, fitted with intermediary 6, 30, 54 and 66 turns’ outputs.
• Power supply cable.
