W  = 
 
 μ* μ0* n^2* l^2* V
/ 2
W =  
 μ* μ0* n^2* l^2* V
/ 2
$$W$$ = $$\frac{\mu\cdot \mu0\cdot n^{2}\cdot l^{2}\cdot V}{2}$$
W =  
 V* l^2* n^2* μ* μ0
/ 2
$$W$$ = $$\frac{V\cdot l^{2}\cdot n^{2}\cdot \mu\cdot \mu0}{2}$$
W =  0.5* V* l^2* n^2* μ* μ0$$W$$ = $$0.5\cdot V\cdot l^{2}\cdot n^{2}\cdot \mu\cdot \mu0$$
