| An iron ball was suspended from the spring of a laboratory dynamometer. Will the dynamometer readings change (and if change, how) if the dynamometer with the ball is placed in a uniform magnetic field, the magnetic lines of which are directed vertically upwards?
Dynamometer readings will not change.
In a magnetic field, an iron ball is magnetized along a magnetic field, but since the field is uniform, the total force acting on the ball from the side of the magnetic field will be zero.
