Question

When you move a magnet towards a coil, it produces a current in the coil. The current flows in the coil in the direction which produces an "induced" magnetic field that pushes away the motion of the approaching magnet. This is called Lenz Law. The faster the magnet approaches, the bigger the current and the larger the induced magnetic field.

Suppose Lenz Law was exactly the opposite: When you move a magnet towards a coil, the induced magnetic field pulls the magnet closer. What do you think would happen?

Explanation / Answer

the effect will essentially be the same(ie.faster the magnet approaches, the bigger the current and the larger the induced magnetic field) with the direction of induced current reversed in both the cases...
