Induction Heating Ice: How Does it Work?

Click For Summary
SUMMARY

The discussion centers on the mechanisms of heating ice using electromagnetic energy, specifically distinguishing between dielectric heating and induction heating. Participants clarify that the process demonstrated in the referenced video is likely dielectric heating, which operates by exciting dipoles in materials like water and ice, rather than induction heating, which relies on eddy currents in metals. The conversation also raises questions about the visual effects observed in the ice, suggesting further investigation into the material properties involved.

PREREQUISITES
  • Understanding of dielectric heating principles
  • Knowledge of induction heating mechanisms

Does anybody know how this works?

Synetos...what's the source of the video??

I am not positive what is happening...that IS a fascinating little video...

I suspect this is an example of dielectric heating,
perhaps at frequencies different from a typical microwave oven?

http://en.wikipedia.org/wiki/Microwave_oven#Principles

not actual INDUCTION heating...
http://en.wikipedia.org/wiki/Induction_heating

The basic difference is that dielectric heating as in a microwave oven heats via dipoles...polarized molecules especially in water but also in fats and ice to lesser degrees... while induction heating accomplishes the transfer of electromagnetic energy via eddy currents in metals...especially ferromagnatic metals...

I have no idea why the ice appears to "glow" internally...
 
Are you sure it is ice? I would think that glass is more likely. Seems like an episode of Mythbusters waiting to happen.
