Question

Two parallel frictionless rails are connected to a constant current source.The source derives a current I when a metal rod of mass m kept on rails.A magnetic field of strength B established downward to the plane of this system.How much the rod will displace before it comes to rest if the length of rails is d and length of rod is L.(Coefficient of friction between rod and group is mu)

Answer 4

@Mashy
alive?

Answer 5

@Mashy if current is flowing in Z axis then using RH rule flux lines will be also passing in that way? :/
