Hall Effect edit
"The result of the phenomenon is that a potential difference is induced normal to both the direction of the magnetic field and the current."
Is that not just the Hall effect? — Preceding unsigned comment added by 129.67.53.138 (talk) 18:12, 21 April 2012 (UTC)
Wrong Temperature Assignment in Picture? edit
There is a mismatch between the pictures of the Hall Effect and the Ettingshausen effect. According to the Hall effect scetch, when B goes from bottom to top and I from background to foreground, the electrons are bent to the left. Hence, the left side should be heated, not the right one. However, in the Ettingshausen scetch, the right side gets warmer. Wassermaus (talk) 10:39, 8 December 2017 (UTC)
- No mismatch! Hari Singh Nalwa "Handbook of Thin Films" ISBN 978-0-080533247 p463, Academic Press says: "Slow electrons tend to suffer a greater deflection than fast ones. Because slow electrons carry less enery than the faster ones, the side where they a deflected will tend to be colder than the opposite one." -- Wassermaus (talk) 16:25, 8 December 2017 (UTC)
