A long straight wire with an orientation perpendicular to the plane of the page, is being pulled to the right with a speed V (along the positive X direction). A uniform magnetic field of magnitude B0 points downwards (along the negative y-direction)
a)Use lorentz law to find the direction of the force felt by the free electrons on the wire. Towards the page or out from the page
b)What is the emf between the ends of the wire, induced by the lorentz force?
Homework Answers
Current should be into the page. By using lorentz law.
And emf is given by e= VBoL where L is the length of wire
