magnification

Pronunciation: mag′ni-fi-kā′shŭn

Definition:

1. The seeming increase in size of an object viewed under the microscope; when noted, this increased size is expressed by a figure preceded by ×, indicating the number of times its diameter is enlarged.
2. The increased amplitude of a tracing, as of a muscular contraction, caused by the use of a lever with a long writing arm, one in which the fulcrum is placed nearer to the muscle than to the writing point.
