When you drop a strong magnet through the center of a copper pipe, what happens to the copper piper and the magnet?

Copper is; unlike iron and steel; not ferromagnetic, but diamagnetic. This means that induced magnetic fields in copper will counter the applied force.

When you drop a strong magnet through a copper pipe, the moving magnetic field will induce currents (Lenz’ Law). These currents will now induce their own magnetic field. This magnetic field counters the falling magnetic.

Result: the magnet will fall way slower than if it was falling through a plastic pipe.

Is there a picture to go along with this

Electoral current force mechanical advantage if the wheel and axle is 2 n and the output force is 20 n
