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.
An electric field has a force proportional to the amount of electric charge within the field, and the force is in the direction of the electric field. On the other hand, force of the magnetic field is proportional to the electric charge as well, but also takes into account the speed of the moving charge.
