  1. 💁🏻‍♀️ ICYMI: ⚡🧲 #Cambridge #math professor Hannah Fry demonstrates how to build a simple electric #motor using a #battery, #copper wire, #magnets, and paper clips.

    Winding wire into a coil creates an electromagnet that repels and attracts the magnet beneath, forcing the coil to spin.

  2. Nice new video showing the hoist of our third toroidal field (TF) magnet for our SPARC tokamak — the fusion demonstration machine we're building at CFS HQ in Massachusetts. These electromagnets (each strong enough to lift a small aircraft carrier) will help hold a superhot cloud of charged particles called a plasma. When those particles collide — that's fusion — the process releases tremendous amounts of energy. youtube.com/shorts/lflVjhWgads

  3. Breaking down #rareearth element #magnets for #recycling
    A team of researchers says it has developed a way of separating #rareearthelements (REEs) from waste—magnets, in this case—that is relatively easy, uses less energy, and isn’t nearly as emissions and pollution intensive as current methods. The team published a paper describing this method in the Proceedings of the National Academy of Sciences.
