# Direction of force without right-hand rule?

Hi guys
I'm not sure if this is the right area - this is my first post - but it seems like it fits so

My question is, is there a way to get the direction of force on a charged particle from a magnetic field without using the right hand rule? What I'm looking for would be a way to just think about it, rather than look at my hands, or imagine my hands.

You could calculate $q\vec v\times \vec B$ [and, if needed, get the components]
