How to prove the radius of curvature at any point on a line?
In a magnetic field, field lines are curves to which the magnetic induction B is everywhere tangetial. By evaluating dB/ds where s is the distance measured along a field line, prove that the radius of curvature at any point on a line is given by
p= B^3 / [ B x( B * del) B]
where do i start with this?? I have no idea what to do
