How to calculate magnetic flux.

[pontussweden]

Hello everybody, Im new to the forum.

For some time i have tried finding out how to calculate the resulting magnetic flux (B) that is created in a coil whit a iron core.
But i cant find any answer, I have lost hope in finding the answer on google.

If someone could give me a exampel i would be very greatful !

Best regards Pontus

There are lots of examples. Google magnetic path, reluctance, permeability, flux and such words. One rather old source is E T Glas "Likströmslära".

Half full - Half empty? I don't mind. It's what in it that counts.

From the URL below… scroll down to around page 168.

Is this somewhat what you’re looking for?

I find this resource useful:

Slides 1 through 10 lead to the development of the relationship between B and current in a coil. Note that the core material is not considered, so you'll have to substitute the relative permeability of iron where appropriate. Also note that "magnetic flux" as you say, is typically denoted [Φ], with B being reserved for "magnetic flux density".

Hello again everybody.

Thanks ( och tack ) for the answer's i should look in to them now.

Have a great Friday.
