Where do I put the at sign?
Too hard, ok, easyer now?
eerin at xylogas.
I read some:
I see now it is posible to magnetize permanet magnet ring correctly. But correctly magnetized permanent magnet field lines keep inside magnet material and don't come out. Such device look like not magnetized.
In magnetazion process field lines that are inside permanent magnet freeze other field vanishes when magnetazion device off. Because correct field is circular, they are imposible to see outside.
only current is posible to make correct field, magnetic energy is stored in vacuum near magnet and magnetic field needs current to stay. it is like moving train. If try switch current off, field keeps current runnig until its energy is consumed -> volts go high until something break.
Ok, but if we have coil of normal copper and same coil is coupled with HTS bulk ring.
What happens when we put current to normal coil and turn it off?
First SC coil make repellion magnet field so reverse current induses it. But what happens when we switch off current?
Things come more complicated because induction depends field rising speed.
I try to ask how induze high teslas to bulk SC ring? Have anybody ideas dos it work or not?
Thousands of small energy pulses, and because all thigs are posible to reverse, how cancel SC field? Throtling posible?
