Rohan dropped a bar magnet into a container filled with iron paper clips. When he lifted the magnet out, where did he observe the maximum number of paper clips sticking?
  1. Only at the exact middle of the magnet
  2. Uniformly spread all over the magnet
  3. Near both the ends of the magnet
  4. Only at the North pole and none at the South pole

Solution

The magnetic force of attraction is strongest near the two ends or poles of a magnet, so maximum paper clips cluster at both ends.
