Explain how gravitational electric and magnetic forces act on a maglev train? Please help!

Question

Assuming you started to the very right of the resister just before the first column of magnetic field lines. As our "train" continues to move with velocity(v) more and more magnetic field lines get introduced into the enclosed area of our circuit.

Lenz's Law: Says any change in the magnetic environment, will cause an induced magnetic field to take over in order to get it back to what it was before.

So our Binduced is coming OUT of the page.

Hope this clears it up for you lemme know if there's any confusion.

It's a bit intuitive but not a challenge if you understand the fundamentals, I just hope my explanation was clear?

The way you can also find the direction of any cross product is by doing the 1-2-3 rule(Or I call it that at least)

EX
$$F_{B} = ILxB$$

1st finger(pointing finger) direction of I
2nd finger(Middle finger) direction of B
3rd finger(Thumb) is always the resultant
