Iv been pondering the ice and the effects it has on an inductor, it seems to decrease resistance therefore it increases the magnetic field.
As heat will destroy a magnetic field or weaken it at least cold seems to increase it, Im not talking about extreme cold but just below freezing,
I froze the c cores with the magnets between the c cores, but I had accidentally reversed the magnets they were repelling each other, they will still attract in this mode through a ferrous medium, anyway it made some interesting fields, but when I thawed it out the core had been broken in several places, I found this puzzling. Did the field get so strong it severed the ferrite?
Some thoughts on ice
Ice has a very high dielectric value, Im no scientist so no numbers but I would guess extremely high, high enough to separate the particles from the field
maybeAlso I think the ice creates a vacuum of sorts.
Ice and its attributes might be just enough to push the right device over the edge.
A thousand designs to find the one that makes total sense, We can bury ourselves in circuit designs and never see the real picture, the circuit only needs to be simple until the right device is found then work the circuit to tune the device.
