why is the force the strongest when current is perpendicular to magnetic field lines from a permanent magnet? I understand the formula F=ILBsinθ and that the force would be greatest at sin90 because sin90=1 but what is actually happening that is making this the case?
Homework Answers
We know theta is angle between length (l) and magnetic field( B).So in actull magnetic field and length are perpendicular to each other ,if one is along x axis then other must be in Y or Z axis .
We can't understand physically How and why magnetic field become greatest,we can understand it mathematically only or experimently in Lab
