Question

the maximum magnificants of electron microscope is??​

Answer 1

About 1.5 million times from the most powerful TEM's (Transmission electron microscopes) and SEM's (Scanning electron microscopes)

Answer 2

A scanning transmission electron microscope has achieved better than 50 pm resolution in annular dark-field imaging mode and magnifications of up to about 10,000,000x whereas most light microscopes are limited by diffraction to about 200 nm resolution and useful magnifications below 2000x.

World's Most Powerful Microscope. Lawrence Berkeley National Labs just turned on a $27 million electron microscope. Its ability to make images to a resolution of half the width of a hydrogen atom makes it the most powerful microscope in the world.
