Greetings everyone(New guy here!). I wanted to know something about "Lorentz force". A magnetic force causes a loop carrying current to rotate and torque is created due to those forces. Are magnetic fields doing work in this cause? Based upon this law: F = q(E + v + B) F = I x L x B (Current flowing thorugh a wire.) I believe its obvious that without the magnetic fields no work can be done. Thus the"motor effect" is caused due to those forces. Is the magnetic field perpendicular to the loop wire? + In general are magnetic fields conservative or nonconservative? Thanks all! You're newly fresh member Miyz!
