Again the forces acting on the two poles of magnet 3

This preview shows page 2 - 3 out of 3 pages.

Again, the forces acting on the two poles of magnet 3 due to magnet 1 are not equal in magnitude. Since the south-pole of magnet 3 is far from the magnet 1, the force acting on it will be smaller than the force on the north-pole of magnet 3. Therefore the net force on magnet 3 will be towards up and right.

Next we consider the force on the magnet 3 due to magnet 2. By following the same chain of reasoning, we can conclude that the net force on the magnet 3 will be towards up and left direction. So the directions of the forces due to magnet 1 and magnet 2 are as following: Magnet 1 - Right and Upward Magnet 2 - Left and Upward Also since the magnet 3 is equidistant from both the magnets, the magnitude of the forces from both the magnets will be same. Therefore, we can conclude that the left and right components of the forces will cancel each other while the forces in upward direction will add up. Consequently the net force on the magnet 3 will be in upward direction. Hence, the net magnetic force acting on magnet 3 will be in upward direction .
