Need bit of help with the exam ive got to sit to pass my first year of uni, dont understand a lot of the work so a little screwed!! Appreciate it if someone could have a look at this and give me a helpin hand. Cheers.

- 300 turns wire wound around annular iron ring, mean radius 30mm, cross section area 20x20mm2. current in coil 0.5A @ 50hz. relative permeability of iron is 500. mu0 (greek letter) = 4 pi e-7.

- find magnetic flux
- induced voltage
- self inductance

Please move to realavent forum, if there is one, and thanks again.

Um... can't you just get out one of your text-books and find the section that explains how to do it?

I'm a Mechanical Engineer and I remember doing that in first trimester Engineering science at college, I don't remember how to do it but I do remember it was easy.
