For my senior year, the school sprang for a FORTRAN compiler to run on the business office NCR computer. My job was to run the students punch-card decks through the computer during the business office lunch hour. Spent an interim month learning to use FORTRAN as a language usage analysis tool, under tutelage of a Classic Languages professor.
electric forces can be attractive or repulsive, whereas gravitational forces are only attractive.
If the charges are in motion, howeverâand in this instance motion or rest is understood in relation to the observerâthen it appears as though a different sort of force, known as magnetism, exists between them. In fact, the difference between magnetism and electricity is purely artificial. Both are manifestations of a single fundamental force, with magnetism simply being an abstraction that people use for the changes in electromagnetic force created by the motion of electric charges.
