• Electric motor, shown in 'How Does an Electric Car Work?' video by Learn Engineering

    It's not surprising that the powertrains of electric cars differ quite a bit from traditional internal-combustion engines. Although they have fewer moving parts, the rare-earth magnets that help power electric cars can be quite complex to fabricate. So, what is there to know about rare-earth magnets—and how do automakers choose which kind of magnet is best for an electric car's motor? DON'T MISS: Better electric motors can boost electric-car efficiency First, there are four main types of magnets: ceramic (ferrite), AlNiCo, Samarium Cobalt (SmCo), and Neodymium (NdFeB). The latter is the...
