Magnetic ink is exactly what the name indicates; it is a kind of ink which is both visible to the eye (it's black) and has a magnetic field that can be detected with the right kind of magnetometer. It is used in the coding on the bottom of checks, known as routing numbers, so that it can be read both by people and by computers.
When you were born!!!
There are two types of global poles; magnetic and geographic. Neither were invented. The magnetic poles are two points on the Earth where the magnetic field is most intense. The geographic poles are the northernmost and southernmost positions on the globe.
In 1951
No. Despite many Internet conspiracy rumors claiming otherwise, US bills do not have magnetic ink, bar codes, or RFID chips. Modern bills $5 and higher DO have special strips that glow under UV light and watermarks, and bills $10 and higher have special inks that change color when you tilt the bill.

Unlike normal ink magnetic ink can be read by humans and specialized equipment. Magnetic ink is often used to print characters, for example routing numbers, on documents which are read by machines.
micr(magnetic ink character recognition)
MICR is used to facilitate the processing of cheques in banking systems. the data is typed in magnetic ink, mostly iron oxide which can be detected by a magnetic ink character reader and processed.
ink gets finished so fast
ancient Egypt invented black ink but ancient china stole it from them.

Black ink was invented in 900 a.d. by the chinese. Ink contains dyes and some powder rocks.
The Chinese Dynasty that invented India Ink was the Cao Wei Dynasty.
Magnetic Ink Character Recognition
MICR stands for Magnetic Ink Character Recognition. OCR stands for Optical Character Recognition. The former uses magnetic ink, the latter doesn't.
