Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]

The scientists from which technological company has created the world’s smallest magnet using a single atom which can store one bit of data on it?

A	TCS
B	IBM
C	Google
D	Microsoft

Explanation:

Detailed explanation-1: -For the first time, a single atom can store a single bit of data. Dr. Christopher Lutz of IBM Research-Almaden in San Jose, Calif. with IBM Research’s Nobel-prize winning microscope he used to store data on a single-atom magnet.

Detailed explanation-3: -The bit is the smallest fundamental size of data storage. It is a binary digit meaning that it can take the value of either 1 or 0.

Detailed explanation-4: -Physicists construct world’s smallest magnet composed of only five iron atoms. (Nanowerk News) Physicists at Hamburg University have constructed, atom-by-atom, the world’s smallest stable ferromagnet composed of only five iron atoms ("Current-Driven Spin Dynamics of Artificially Constructed Quantum Magnets").
