Do magnetic things fall faster?

Within a room size volume, the magnetic field of the earth is uniform. A magnetic dipole only experiences a net translating force in a non-uniform magnetic field. (And that depends on its orientation.)

To put R.W. Bird’s answer into layman terms, and expand on it slightly:

1. The Earth’s magnetic field can be safely treated as uniform within a region the size of a room.
2. A uniform magnetic field does not affect the way an object moves (it can only rotate an object), and therefore does not affect the way an object falls.

No, the gravitational acceleration is almost same for each body at one place... and also the Earth's magnetic field can only rotate a magnetic object and can not make it fall faster...
