Lenz's Law and Gravity

A mass \(M\) pulls the conducting bar through a vertically oriented magnetic field.

A mass \(M\) pulls the conducting bar through a vertically oriented magnetic field.

In the above picture, a mass \(M\) falls under the influence of gravity, pulling with it a conducting bar of mass \(m\), resistance \(R\), and length \(\ell\) that sits on a U-shaped piece of metal in a vertically oriented magnetic field perpendicular to the plane of the U, pointing in the positive-z direction. In which direction does the induced current flow?
