The bar in figure Q31.5 moves on rails to the right with a velocity, v, and the uniform, constant magnetic field is directed out of the page. Why is the induced current clockwise? If the bar were moving to the left, what would be the direction of the induced current?
(The figure is at the bottom of page 24 in the document linked below)
My answer is;
As Lenz's law states that the induced current in a conductor acts in the direction that opposes the charge that produced it. Consequently, the magnetic field is acting into the page, meaning that the induced current is clockwise (by the right hand rule).
If the bar was moving to the left, the induced current would be counter-clockwise.
If this correct?
Thank you for any help =)
