Lesson 14: Magnetism History Today we really take magnets for granted... have you ever asked yourself why they can stick to your fridge? The history of magnetism begins with the ancient civilizations in an area known as Asia Minor (around modern day Turkey ). In a region known as Magnesia rocks were found that would attract each other. These rocks were called "magnets". For a long time magnets were thought to be somehow magical, and were treated as a novelty (they weren’t used for anything serious). Eventually it was discovered that a magnet suspended from a fine thread will spin on its own until one pole (end) of the magnet is pointing toward the north. The same pole always ended up pointing north. The pole which points north is called the north pole; the other pole that points south is called the south pole. All magnets have a north and a south pole, no matter what shape they might have been bent into. The magnetic field is the strongest at these poles.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
