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?
Current should be into the page. By using lorentz law.
And emf is given by e= VBoL where L is the length of wire

A long, straight wire carrying a current of I1 =5.0 A perpendicular to the xy plane (page on a table) intersects the x-axis at the origin and points +z direction (out of page). A second, long wire carrying I2 = 12 A intersects the x-axis at x= 6.0 cm and points -z direction (into the page). Find the direction and magnitude of the net magnetic field due to these two currents at (x=0, y= 8.0 cm). First draw a neat...
