5. magnetic pole

6. electric attraction. first to explain the operation of the magnetic compass. English scientist and physician, was born on May 24, 1544 in Colchester, England

7. Joseph Henry His experimental work in chemistry, electricity, and magnetism reflected only a small portion of his broad scientific interest. Discovered the phenomenon of self-inductance. He invented a galvanometer and theelectric motor. The unit of inductance, called ``henry,'' immortalizes his name. American physicistand scientificadministrator, was bornonDecember 17, 1797 in Albany, New York.

8. Charles Augustin de Coulomb known for the formulation of Coulomb`s Law. Coulomb is distinguished in the history alike of mechanics and of electricity and magnetism. Studyonfriction Coulombic force is one of the principal forces involved in atomic reactions. The coulomb, a unit of electric charge, was named in his honour. French physicist, was born on June 14, 1736 in Angouleme, France.

9. Michael faraday Studiedelectromagnetism and electrochemistry. Discoveredelectromagneticinduction studied on electrolysis and discovered two fundamental laws that bear his name: Ley de Faraday: Mass = electrochemical equivalent, by the intensity and time (m = cIt). Farad (F): unit of electrical capacity of SI units. English chemist, natural philosopher and physicist , was born on August 25, 1867 in London, England
