Hi,
This is not homework, I'm just confused:
I have been asking on the electrical engineering forum about calculating 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.
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.
How do they calculate this to get 100 as the answer?
Thanks
