This clip demonstrates the effects of various neodymium magnets on a CRT television screen, set to a fast-paced electronic synth track. It starts around 0:02 with a small 15mm neodymium sphere moved across the glass, causing distinct swirls of red, green, and blue distortions wherever it passes. At 0:36, a chain of magnetic spheres is stretched into curves and rings across the display, generating intricate wave-like interference patterns. The experiment ramps up at 1:35 with a much larger 50mm disc magnet that distorts large sections of the picture and creates deep dark rings in the center of the magnetic field.
The finale around 3:12 brings out a massive multi-magnet block strapped together with bracket mounts. Even from a foot away, the magnetic field is strong enough to completely bend the electron beam, pulling the entire menu display into a warped smear and causing massive color shifts across the screen.
It is always mesmerizing to watch magnetic fields visually mapped out in real time through a CRT tube, though anyone who grew up around these monitors knows the lingering dread of permanently magnetizing the shadow mask. The soundtrack gives it an energetic retro feel, making it an entertaining look at physics distortion in action.
