Today (May 13, 1878) is the Memorial Day of American scientist Joseph Henry, who invented the technique of making a powerful electromagnet.

Today (May 13, 1878) is the Memorial Day of American scientist Joseph Henry, who invented the technique of making a powerful electromagnet.

On December 17, 1797, Joseph Henry was born in a poor family in New York City, USA. His father, who worked as a laborer 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.
