A metal bar moves with constant speed to the right. A constant magnetic field points out of the page. What happens to the electrons in the bar (in the frame of the moving bar)?
One end of rectangular metal loop enters a region of constant uniform magnetic field B, with initial constant speed v, as shown. What direction is the magnetic force on the loop?
One end of rectangular metal loop enters a region of constant uniform magnetic field B, out of page, with constant speed v, as shown. As the loop enters the field is there a non-zero emf around the loop?
