Calculation: 3FaDWY - 1

W =

μ* μ0* S* N^²* l^²

/ ( 2* l)

W =

μ* μ0* S* N^²* l^²

/ ( 2* l)

$W$ = $\frac{\mu\cdot \mu0\cdot S\cdot N^{2}\cdot l^{2}}{2\cdot l}$

W =

N^²* S* l* μ* μ0

/ 2

$W$ = $\frac{N^{2}\cdot S\cdot l\cdot \mu\cdot \mu0}{2}$

W = 0.5* N^²* S* l* μ* μ0 $W$ = $0.5\cdot N^{2}\cdot S\cdot l\cdot \mu\cdot \mu0$
