Answer:
Elastic after effect:-)
The body return to their original state on the removal of the deforming force. Some bodies return to their original state immediately after the removal of deforming force while some body take longer time to do so. The delay in regaining the original state by a body on removal of the deforming force is called elastic after effect.
ln Galvanometer, suspensions made by quartz or phosphor-Bronze alloy are used because their elastic after effect is small. on the contrary, glass fibre take hours to regain its original state
