This Thermocouple demonstrates thermoelectric effect. A small current is detected when a welded junction is heated. Comprises a copper / constantan junction with leads attached.

(Wikipedia excerpt: .."...A thermocouple [T] , also known as a "thermoelectrical thermometer", is an electrical device consisting of two dissimilar electrical conductors forming an electrical junction. A [T] produces a temperature-dependent voltage as a result of the Seebeck effect, and this voltage can be interpreted to measure temperature. [T] are widely used as temperature sensors.[1]

Commercial [T] are inexpensive,[2] interchangeable, are supplied with standard connectors, and can measure a wide range of temperatures. In contrast to most other methods of temperature measurement, [T] are self-powered and require no external form of excitation. The main limitation with [T] is accuracy; system errors of less than one degree Celsius (°C) can be difficult to achieve.[3]

[T] are widely used in science and industry. Applications include temperature measurement for kilns, gas turbine exhaust, diesel engines, and other industrial processes. [T] are also used in homes, offices and businesses as the temperature sensors in thermostats, and also as flame sensors in safety devices for gas-powered appliances....").
