Color Gradient Magnetic Film: a favorite device in my collection- making the invisible visible and revealing the hidden beauty of the physics in our everyday world. The field structure of six magnetic objects can be seen here. Staring with a simple dipole neodymium in the center and going clockwise from the top left: fridge magnet with stripe pattern, magnetic rotor of a small motor, ring of poles of a rotor for a stepper motor, vintage ferrous classroom “dipole”, and a coded interlocking neodym

Magnetic Poles of Refrigerator Magnets: visualizing the invisible with color gradient magnetic viewing film- the secrets of refrigerator magnets revealed: strips of north and south poles. Compared to the two poles at the end of the horseshoe magnet 🧲 the collection of parallel strips seen in the fridge magnet is a special orientation of the magnetic poles called a Halbach array, which allows for the combination of poles to create a strong magnetic field on one side and a very weak one on the ot
