Re: Multi layer coil design

Hello again, So all you want to do is produce a strong magnetic field then using the coil? Hi Mr Al, YES...indeed..... Controllable magnetic field with low power , low losses.... and also want measure how strong it's if possible.......any suggestions.or..comments.... Let me know the general applica...

Re: Multi layer coil design

Hello again, Im still not exactly sure what you are asking here. You show a DC to DC converter with the apparent output going to the coil, but dont say what you are using that coil for exactly. Is that part of the converter or is that a separate filter? Hi Mr Al, Sorry, I drawn wrongly, I was plann...

Re: Multi layer coil design

Hi again, Are you saying you want to use an H bridge and Buck or do you want to do it another way? I think i can help better if you should me a schematic of what you want to do, or describe it in detail. HI Mr Al, I am looking for better solution... ofcourse... with low power consume and less cost....

Re: Multi layer coil design

Hi MrAl, Again..Thanks for info... finally I found inductance of the coil without iron core 3mH and with slug it is 600mH. So, I guess I need to consider the 600mH to find the capacitor value with frequency, correct me if I am wrong. I am designing ckt to run this coil @100mA current and 12V . By co...

Re: Multi layer coil design

Hi there, So you see, the permeability of the core is a very important piece of information that we really need to work this out. The permeability can be measured, but it's just as simple to measure the inductance and not be bothered with the permeability. To measure the inductance you need a good ...

Re: Multi layer coil design

Hi there, Thank you for your detailed reply.. Although you gave quite a bit of information in your question unfortunately it still isnt enough. To calculate the inductance (or at least to estimate it) of an iron core inductor we also MUST know the permeability of the core. The permeability (abbrevia...

Multi layer coil design

Hi :smile: , I got multilayer iron core coil , which has 5000 turns, 100mm iron rod( but coil winded 82mm only) and diameter 19mm. 0.315mm Copper wire used for winding. i want to findout L inductance of the coil, I gone through dfferent soucres which contain air core coil multilayer calculation, no ...
