M Miki23 New Member Dec 7, 2019 #1 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

rjenkinsgb Well-Known Member Most Helpful Member Dec 7, 2019 #4 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. Reference: **broken link removed**

M Miki23 New Member Dec 7, 2019 #5 Thanks, but this is for air core as i understand? And length of coil doesnt matter?
