When an eraser is rubbed with wool, it becomes charged with static electricity. This charge can attract small pieces of paper due to the phenomenon of electrostatic attraction. The rubbing action transfers electrons from the wool to the eraser, giving the eraser a negative charge, which then attracts the positively charged paper bits.
