In this magnetic experiment I show you how using a Halbach array can double the power of the magnets. This particular arrangement of the magnets, bound by means of glue allows to almost double the magnetic field from an array side while the other side the magnetic field is almost zero. The array of Halbach find practical applications in the Maglev train and in particle accelerators. | Magneticgames

The most magnetic stars ever discovered are rewriting astrophysics. Magnetars unleash unimaginable forces — their magnetic fields are trillions of times stronger than anything we know, powerful enough to stress star crusts, trigger violent starquakes, and produce giant bursts of X‑rays and gamma rays. NASA telescopes have even tracked magnetar outbursts and measured polarized X‑ray light, shedding new light on how these objects behave and how they may be linked to mysterious fast radio bursts se

Electric arcs at 20,000 volts in a magnetic field can take fantastic forms. See how the shapes of the electric arcs change depending on the magnets used, it's fascinating. | Magneticgames
