Question

Quizplus · Accepted Answer

The probe tip of a scanning probe microscope hovers above the surface of the sample being studied, without etching or chemically changing the atoms. It uses a tiny electric current or force to sense the surface of the sample and create a topographical image. There is no magnetic field injection in this process.
