Lorentz force questions

[aladinlamp]

Hi

i have 2 questions regarding Lorentz force

1. Does Lorentz force create opposite and equal reaction force acting on magnets, as you can see on attached picture <?


2.Does conductor moving in homogeneous magnetic field consume more power than  static condtuctor to  achieve same continuous amperage?  Does the wire movement increase power input <>?

Thanx for clarification

On your first question the answer is yes. On your second question either you move the magnet or the wire you can get the same amount of drag thats why the electrical power output from wire is always less than the mechanical power input.

what do you mean by drag <?

i was asking if relative motion between wire and magnets increases power input compared to static scenario.

what do you mean by static scenario?

[aladinlamp]

static i mean, wire and magnets are hold in place, even if they want to move from each other
