This course has some deep concepts, which are normally not very obvious. A number of 3D visual images and animations help to grasp the difficult conceptual part quite easily.
Following topics are covered:
1) Bar magnet and its magnetic poles
2) Magnetic Length versus Geometric Length of bar magnets
3) Magnetic Moment of a bar magnet
4) Torque, Work Done, and Energy for a bar magnet placed inside another magnetic field
5) Magnetic Field around a bar magnet
> case 1) at any point along the axis
> case 2) at any point on the perpendicular bisector
