Electromagnetic Angular Momentum
... Now that everything appears to be well settled, I will leave you with two questions to worry about. First, let us take one more look at the final configuration. The solenoid has no current and it produces no magnetic field. But we do have a ring of charge which is rotating around, which constitutes ...

Newton`s Laws
... Newton’s First Law of Motion First of all, realize that this law isn’t really Isaac’s – It’s Galileo’s. In the early 1600’s, Galileo suggested that, once an object is in motion – no force is needed to keep it in motion. Force is needed only to change the motion of the object. This is a time period ...
