Two bars of the same size, one made of soft iron and the other made of steel, are placed inside a solenoid. A large direct current is passed through the solenoid to magnetize both bars. The current is then switched off and the bars are removed. Each bar is then brought near a pile of small iron paper clips.
What is observed?
Both bars attract the paper clips.
Neither bar attracts the paper clips.
Only the steel bar attracts the paper clips.
Only the soft iron bar attracts the paper clips.
