The HIDDEN Magnets in Your Phone ft. MKBHD

The video features MKBHD and Dianna from Physics Girl exploring the use of magnet paper to visualize magnetic fields in various devices. They discuss the properties of magnet paper, how it reveals magnetic fields, and demonstrate its application on devices like the iPad and Galaxy S10. The video also covers the concept of Halbach arrays, explaining how they create a magnetic field on one side but not the other. The hosts engage in hands-on experiments, showcasing the science behind magnets and magnetic fields.
