Is there a simple mathematical way of proving the left hand side equals the right hand side (see attached image)?
Any help will be much appreciated as I'm desperately trying to work out exactly where the magnetic Reynolds number comes from. I can derive the left hand side (its simply the ratio of advection term to the diffusion term which themselves can be derived using Maxwell's equations) but I am stuck at this final step as I'm not very good at vector calculus.
Thanks in advance for any help.
