yes sir, i am a slow learner, i am reading your first link again and again, i will ask if any doubt araises...

informative ...

hmmm...I might be wrong, but is there any chance that the copper electrons which have magnetism(due to spin) all align in direction opposite to that of applied field there by making B=0 in the core, also more importantaly, why does this effect look very similar to Meissner Effect where the...

When you try to create time varying magnetic fields in solid metals, there is severe heating due to eddy currents, when you increase the frequency, just like in NDT(non destructive testing) the magnetic field is pushed away from the core to the periphery due to eddy currents opposing the field...

why are you worried about the engineering and design constrains instead of answering for the concept alone ? .Imagine an air cored 3 phase coil system that produces rotatory magnetic field except that the frequency is in Mhz range, now you can cut any other conductor by placing it inside the...

if they are not free then they might have a gyromagnetic ratio slightly different from that of a free electron, but rest of the process remains the same.

Imagine a magnet moving up and down so that its flux 'B' cuts the copper rod to produce an alternating emf, suppose if the movement is fast enough such that its frequency equals to the electron spin resonance frequency given by F = B x 2.8 Mhz per gauss, neglecting skin effect, more copper...

thanks for clarification...

so we can have the RF coil wound around the magnets, such that their fields are along same axis right ?

understood

we do projects for educational purpose, This particular Problem came while working on differential mode choke to reduce noise input in electronics, it would help me a lot if someone answers it.

No

Thanks, Your guidance saves me hours of Experimentation, i found the links useful. Is there any books/links to solve and design NLTLs ?
