The next half of this course, magnetism, looks at how moving charges interact with other charges and their environment. Something to keep in mind as you go along are the equations you learned in electricity; the equations in magnetism are very similar. You most likely have seen a magnet before and know their anatomy (a north and south ‘pole), and that they attract or repel metal objects or other magnets depending on orientation. As with electricity, magnetism can be diagrammed through magnet field lines, and its also important to note that these lines are a closed loop that go out from north and into south. No matter what line comes out of the north pole, it will always come around and into the south pole. Later, youll delve deeper into what you can do with knowledge of how magnets work.
All magnets have a north and a south pole. There are no magnetic monopoles.
Like poles repel, opposite poles attract.
Magnetic field lines make closed loops and run from north to south outside of the magnet.
Compasses are magnets which are free to align themselves with the net magnetic field.
Magnetic permeability is a material property relating to the ratio of the magnetic field strength induced in a material to the magnetic field strength of the inducing field. Highly magnetic materials have high magnetic permeability.
The magnetic dipole moment (or magnetic moment) of a magnet refers to the force that a magnet can exert on moving charges. It is analogous to the strength of a magnet.
Lecture Slides are screen-captured images of important points in the lecture. Students can download and print out these lecture slide images to do practice problems as well as take notes while watching the lecture.
