N=600 (number of loops)
δ=1,5mm or l0
S0=1,1*S (Cross sectional area)
I need to find energy of toroid and currect going through it.
Solution: W=4,08J, I=6,44A
2. The attempt at a solution
So far I managed to calculate S and S0:
I tried to find energy using this formula but it's not correct:
W=B*H*S*(l-l0)/2 (B and H are from the graph)
Formula for current is I=NH/l but since nothing is correct I didn't bother to try and calculate it.
