need resources for solenoid studies, AC and transient

solenoid theory

Hello all,

I'm trying to find ressources for solenoid studies (I mean long cylindrical inductances), AC and transient.
I remember my first physics lessons, but I can't remember what's happening when I insert a solenoid in another bigger one, "voltage, current, flux, parasitic effect" 'ly speaking.

Any help, any pdf or weblink will be very appreciated.

Thanks a lot.

Regards

Re: Solenoid theory

Maybe this help. But it is solenoids with cores.

The bibliography at the end of page can also help.

Cheers

Solenoid theory

Thanks for your answer hakeen.
In fact, my question is more about "what's happening when you slide one solenoid in a bigger other one".
But the theory aspect of magnetism in solenoid still interesting.

Solenoid theory

It's not clear to me, if you want an exact calculation of the respective field and derived quantities (e.g. self and mutual inductances) or just a qualitative understanding of the behaviour?

Sliding one coil has only an effect, if the flux linkage is changed.

An exact calculation, that's my goal... but I wouldn't ask you to do my whole duty

An exact calculation can be done by integrating the respective field equations. You most likely find a discussion in a theoretical electrical engineering text book. Today, most engineers prefer a numerical solution. For the axially symmetrical case, more simple 2.5-D tools as QuickField can be used.
