I read this book called Practical Electronics for Invetors,and it says that one of the ways to increase magnetic field strenght of solenoid is to increase the current or increase the number of turns.
That got me thinking,why do induction heaters and induction coupled plasma use small number of turns and high current? Why not increase the number of turns and then decrease the current so there is less problem with coil overheating?
I played with online solenoid magnetic field strenght calculator,and as I kept increasing number of turns it kept giving stronger magnetic field without increasing current.So logicaly that extra energy must come by voltage right? I mean energy doesnt just magicaly appear out of nowhere,and since the current stays the same,it must mean that solenoid with more turns needs higher voltage,is that correct?
Can I avoid heat problems by using solenoid that have large number of turns so I can power it with high voltage low current instead of low voltage high current that conventional solenoid with small number of turns would require?
edit : I want to say big thanks for all of you who came here to help me,I didnt expect so much help so fast,this ElectronicsEngineering section seems friendliest of all stackexchange sections I tried,I love you all <3
