## Homework Statement

[/B]

N=600 (number of loops)

a

_{1}=200mm

a

_{2}=240mm

h=40mm

δ=1,5mm or l

_{0}

S

_{0}=1,1*S (Cross sectional area)

B

_{0}=1,2T

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

2. The attempt at a solution

So far I managed to calculate S and S

_{0}:

S=(a

_{2}-a

_{1})*h

S=0,0016m

^{2}

S

_{0}=1,1*S

S

_{0}=0,00176m

^{2}

I tried to find energy using this formula but it's not correct:

W

_{0}=B

_{0}

^{2}*S

_{0}*l

_{0}/2*μ

_{0}

W

_{0}=1,51J

W=B*H*S*(l-l

_{0})/2 (B and H are from the graph)

W=4,76J

Formula for current is I=NH/l but since nothing is correct I didn't bother to try and calculate it.
