Where does the magnetic pressure formula B²/2μ₀ come from?

[Vrbic]

I have seen a formula for magnetic pressure $P_M=\frac{B^2}{2\mu_0}$ Where does it come from? How my I derive it?

Mostly only the using this formula but not much what is behind.
I'm reading something right now but for me is nice to discusse it with others. In few hours I would write my attempt and ask around. That's my way.
