About Thomas Johann Seebeck
- Thomas Johann Seebeck (German: ['to?mas 'jo?han 'ze?b?k]; 9 April 1770 – 10 December 1831) was a Baltic German physicist, who, in 1822, observed a relationship between heat and magnetism.
- Later, in 1823, Ørsted called this phenomenon thermoelectric effect. Seebeck was born in Reval (today Tallinn, Estonia) to a wealthy Baltic German merchant family.
- He received a medical degree in 1802 from the University of Göttingen, but preferred to study physics.
- From 1821 to 1823, Seebeck performed a series of experiments trying to understand Ørsted's findings from 1820.
- During his experiments, he observed that a junction of dissimilar metals produces a deflexion on a magnetic needle (compass) when exposed to a temperature gradient.
- Because Ørsted had discovered that an electric current produces a deflexion on a compass transversal to the wire, Seebeck's results were interpreted as a thermoelectric effect.
- This is now called the Peltier–Seebeck effect and is the basis of thermocouples and thermopiles.
