SUMMARY

The discussion centers on Lenz's Law and its application to a moving bar in a magnetic field. When the bar moves to the right in a uniform magnetic field directed out of the page, the induced current is clockwise due to Lenz's Law, which states that the induced current opposes the change causing it. Conversely, if the bar moves to the left, the induced current becomes counter-clockwise. The right-hand rule is employed to determine the direction of the induced current based on the motion of the bar and the magnetic field orientation.

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 =)

For a moving conductor in a magnetic field can't you just use that the force on a charge q is F = q*VXB and this force causes a current?

The picture didn't load here when I clicked on the link, but I can imagine what it was.

You kind of just assert what the answer is. Can you explain in a bit more detail how you know the induced field points into the page?
