My Mom's induction cooker stopped working so I had a look at it. Opening it up I found this;
Unfortunately I was able to fix it so didn't get a chance to measure the coil. I'm sure it has
real low resistance but not sure about inductance. It's 20 turns but the radius goes down a lot
from start to finish. It appears to use some kind of LITZ wire for low resistance probably.
I'll have to find one at a yard sale so I can do some experiments with it. Does anyone have any
experience with these things? Are they high enough inductance to use on a PI detector?
I think you can get a new one for around $30 at a dollar type store.
Hmm Here's a use one Coil only for $30; http://www.ebay.com/itm/Induction-Co...AAAOSwrklU-5Z8
I found this online - The coil measures about 55uH with no metal nearby and about 25uH with a big
steel cooking pot sitting on it. So probably not to useful for a metal detector but maybe the coil form
could be used?
