Magnet rolling down copper plane: how will it roll?

A strong magnet is moving on a copper inclined plane a Earth magnetic field. If the magnet starts from the middle of the top, the trajectory of magnet is a line, but the velocity of magnet decrease.
If the magnet starts from the left or right side of the top, the trajectory of magnet is not a line, but is a curve. The magnet moves as a drunk magnet.
