While you've indicated a desire to assemble a 'linear motor' you have not advised us as to its application...i repeated it ... how many times ?
I heard that, but does that mean that the voltage doesn't effect it in any way?And we have given you the answer already.
It is not the voltage.
It is the current that matters.
Only to the extent that it (i.e. the increased EMF) 'drives' a greater current through a given impedance...question is and was, does changing the voltage to highest effects the strength of an el. magnet in any way
Assuming I correctly interpret the quoted text:higher voltage released trough the coil can create a short lasting movement of More current
Theoretically, yes... In practice, however, the field will not be as uniform as we'd like...Can Helmholtz coil cancel permanent magnets magnetic field ?
I'm not certain I understand your question... High 'voltage' storage batteries are feasible, however their reliability is poor owing to corollaries of (accentuated) 'gradient distribution' across unmatched cells... Note, also, that, as is the nature of electrochemical devices, even perfectly matched cells won't 'stay that way' for long...is there a battery on high voltage that can survive charging under higher voltage. for example 300 v output , and can be xharged under 350 0r 400 -500 v -1000 v-2000 v etc, thank you.
Such a battery could be assembled via 'stringing' multiple identical cells/batteries in series -- For reasons brooked in my previous post, however, I do not advocate this (inasmuch as you would almost certainly damage one or more cells via over-current owed to 'uneven' charging and/or 'load sharing')...I don'y know if I understood you all, but i see what you mean . how can I find those batteries ?
If it works - it works! Though I'm surprised! --- I've seen such an arrangement (in my case a nominal 120v DC switch-gear ctrl backup) comprised of a qty of 10 12v 'motorcycle' LAs -- howbeit with a (perfunctory) semi-annual 'change-out' schedule... Have you experienced long-term reliability with your installation?There should be no issue connecting batteries in series for higher voltage. I used a string of 17 12V lead acid batteries to get 204V on a project. However, I did charge the cells in parallel to equalize the charge before connecting. After that, they were charged in place.
