Question about magnetic field

[Miki23]

Can someone please give me an example how would i make a coil of 10mT on an iron core of r=0,5cm, with pulsed current, or ac. So, how many turns, length and current. Thanks

Google: inductor calculator Tesla

then play with values until you get what you need.

Its showing just inductance calculators, can someone help me with exactly a what im asking? Thank you

Very approximately, one ampere-turn is equal to 0.1 milli tesla.

That means you need around 100AT to get a 10mT field. eg. 100 turns at 1A, 1000 turns an 100mA, 10,000 turns at 10mA.

Thanks, but this is for air core as i understand? And length of coil doesnt matter?

youre just not looking hard enough (or you tried using Bing.com)...

Thanks a lot! I found just some of calculators that doesnt work good, idk how i missed this one
