If you need help visualizing magnetic fields, these slow-motion video captures should educate or captivate you. Flux lines are difficult to describe in words, because magnet shape and strength ...

Bar magnets and horseshoe magnets are two of the most common shapes of magnet. The magnetic field is shown by lines with arrows that point from north to south. You can tell how old some coins are ...

A much less obvious implementation is a second-order radial flux coaxial magnetic gearbox. It works similar to a normal planetary gearbox, with an outer and inner wheel containing magnets ...

the line source math isn't relevant, and can effectively be ignored. Besides, relatively speaking, MagSafe magnets are very weak And, the main term when figuring out magnetic flux exposure is the ...
