Hi All,
I am trying to cacalculate the strength of electromagnets.
After some searching i have found the equations but i just can't quite get a handle on some of it?
They have an iron core C shaped electromagnet 15cm long & 1cm square in area with a 1cm air gap & the permeability of air is 1 in this example.
They write: The reluctance of the air gap is 1 centimeter divided by 1 times 1 square centimeter.
The answer they have is 100 henries per meter.
(1 centimeter) / (1 * 1 (square centimeter)) = 100 m-1
How do they calculate this to get 100 as the answer?
I noticed that Reluctance is in Henries per Meter but the above calculation is in Centimeters so i assume the answers i have been getting are actually Henries per Centimeter, do i simply multiply the answer by 100 to change it to meters & then the answer is in Henries per meter & seem correct?.
Any help will be greatly appreciated
