# Magnetic Shampoo

If ever I decide to do something to spruce up my looks, this would be the first thing I buy

$E = -\vec{\mu } \cdot \vec{B}$
Although the equation does look fishy to me. Any physicist can enlighten me?

E is the energy associated to the torque felt on an electron with magnetic dipole moment mu in a magnetic field B. For more info, you can check out this website:

where they use U(Theta) instead of mu.
Though I’m confused what it has to do with my hair….

thanks for the tip. I see (from your site) that you are working on L-series and stuff, that’s great!
