A short bar magnet of mangetic moment `5*25xx10^-2JT^-1` is placed with its axis perpendicular to earth's field direction.  At what distance from the centre of the magnet, is the resultant field inclined at `45^@` with earth's field on (i) its normal bisector, (ii) its aixs? Magnitude of earth's field at the place `0*42G`. Ignore the length of the magnet in comparison to the distances involved.
