When we wear the sweater, the wool comes into contact with our bodies, causing friction as the body rubs against the wool. As a result of the rubbing, the wool becomes charged, and a force is felt between the wool and our bodies. During the winter, we hear a crackling sound as we remove our sweaters due to this force.
