Today (December 17, 1797) is the birthday of American scientist Joseph Henry, who invented the technique of making a powerful electromagnet.
Joseph Henry was born on December 17, 1797, in a poor family in New York
City, USA. His father, who worked as a labourer in boats, died at the age of 9.
Later, she grew up in a grandmother's home in Galway. He was educated at the
school there. The school was later named after him. Back home with her mother.
He stopped studying because of poverty and worked at the grocery store. She
joined the watchmaking company as a 13-year-old. He was more interested in
reading the book. He will read any book in his hand. A man who came to his
mother's hostel at home was fascinated by his reading. He gave the book several scientific lectures. Excited to read it. It has changed the course of
his life. The pursuit of science was born.
In 1819 he was given a free course at the Albany Academy. He took the
tuition class for students and made money. He graduated in 1822 with lessons in
mathematics, physics and chemistry. He also worked as a lab assistant at the
same academy. Later, he was appointed Professor of Mathematics and Natural Philosophy.
Soon, I had the opportunity to do scientific research. He studied the earth's
magnetic properties, electricity, and general magnetism. He found a powerful
electromagnetic device that wrapped the insulated wires tightly around the iron
core. Using this, he produced the world's strongest, most powerful
electromagnet weighing 1500 kg. During the experiment, he discovered the
electromagnetic phenomenon, self-induced. In 1832 he was appointed professor at
Princeton.
He found the need for a high voltage battery to drive electricity
through a long wire. It found that high voltage electricity can be transmitted
over long distances and can transmit signals over long distances. Using this
technique, the driver and the doorbell of the telegraph and electric gate were
interpreted. But they are not trying to patent them. In his discovery of the
telegraph, Samuel Morse aided. Although he was the first to discover the
transfer trigger, Michael Faraday was overtaken by the early release. He
designed the electric motor just as Faraday designed it during the same period.
This is what modern DC is all about. Known as the forerunner of motorsport. He
found several important theories on electricity.
He is an American scientist who served as the first secretary of the
Smithsonian Association and a founding member of the National Association for
the Promotion of Science. The electromagnetic gadgets he created were the basis
of the practical electric cables that Samuel Morse and Sir Charles Weichsdon
found separately. Born into a poor family and raised as a world-renowned
scientist by his talent, Joseph Henry left the world on May 13, 1878, in his
81st year, in Washington, DC, USA.
