WILLIAM STURGEON Creator of the Electromagnet CHILDHOODEARLY CAREER

WILLIAM STURGEON Creator of the Electromagnet

CHILDHOOD/EARLY CAREER Cobblers Apprentice • Hated his job • Ran away to join the army Joined the Royal Artillery • Had very little education • Borrowed books and educated himself 1820 -1825 • Retired from the military • Ran a boot repair shop during the day, and gave physics lectures during the evening.

MOVING UP TO THE BIG LEAGUES • He began lecturing at the East India Company’s Royal Military College on science and philosophy in 1824 (where he created the practical electromagnet. ) • Creation of the electromagnet allowed for the construction of many modern basic technology. Like the electric motor and telegraph • He began lecturing at “The Gallery” and his lectures became very popular. • Sturgeon tried to make his lectures fun for the public(mostly for funding from the public, but still a nice gesture!)

ELECTROMAGNETICS

INFLUENTIAL PEOPLE IN ELECTROMAGNETICS Hans Christian Orstread Michael Faraday André-Marie Ampère • • English physicist and chemist • Built extensively on Orstreads work. • Considered by most to be the “greatest experimentalist who ever lived. ” • His greatest contribution to science by rigorously applying mathematics to the study of electromagnetism. • “He was the first to produce an electric current from a magnetic field, invented the first electric motor and dynamo, demonstrated the relation between electricity and chemical bonding, discovered the effect of magnetism on light, and discovered and named diamagnetism, the peculiar behavior of certain substances in strong magnetic fields. ” • Credited for proving there was a connection between electricity and magnetics He found that the magnetized needle of a compass was deflected whenever the electric current through a voltaic pile(an early form of the battery)
