Induction Heating through Ice (1000 C) 

This video showcases a workpiece heated by induction frozen in a block of ice. This is an excellent example of the power of induction heating. Despite the cooling effect of the ice, graphite workpiece is heated up to 1000 C, without melting the ice(not at least quickly).Since the ice is not conductive and its thermal conductivity is also poor, it stays mostly frozen and does not heat up. Also the absorption coefficient for ice is low ( it let's trough the heat ), therefore it does not heat up quickly.

Video tiek skaisti ilustrēta indukcijas sildīšana. Grafīta gredzens, kas iesaldēts ledus klucī, tiek karsēts līdz 1000 C, taču ledus praktiski nekūst. Tam ir vairaki skaidrojumi. Pirmkārt, ledus ir elektriksi nevadošs līdz ar to siltums tajā neizdalās, kā arī ledus kā materiāls arī salidzinoši slikti vada siltumu. Un visbeidzot ledus praktiski neabsorbē siltumstarojumu . Visu šo īpašību summa padara šādu demonstrējumu iespējamu.
