Polarity of the Rod There is a very important topic in EMI called Motional emf. There is a specific use case where the Rod moves over between the Rails. We know that when this Rod moves in the Perpendicular...
It states that if net torque acting on an isolated system is zero, the angular momentum remains conserved. Since Torque is equal to the rate of change of angular momentum so when torque is zero, dL/dt=0 So,...
