Electric currents create magnetic fields. Moving magnets induce electric currents. These principles underpin 95% of global power generation, 50% of wind turbines, motors that comprise 45% of electricity use, heat pumps, and electric vehicles. But what actually are magnets? How are they measured? Why do so many use Rare Earth metals? This 15-page overview of magnets explains key magnet concepts for the energy transition.
