1. if the earth's horizontal field component is 40 µT north,find the magnetic moment of a short bar magnet 0.5m to the west of the compass which deflects the compass needle 45°
2. the magnetic flux density around a long staright wire parallel to the z axis given by B=Φ10/rT.Find the magnetic energy density at a distance of 2m from the wire
3.(a)how does the translational force between two small bar magnets vary as a function of theri seperation?
(b)is their relative orientation a factor?
