Electricity flows through the stator coils, creating powerful electromagnetic fields with alternate polarities. Jay Leno, Popular Mechanics, "How to Keep Classic Cars Road-Ready," 12 Dec. 2012 In other designs, the magnets can be embedded in the stator, or the magnets can be arranged to work with a DC magnetic field. Megan Geuss, Ars Technica, "Toyota’s new magnet won’t depend on some key rare-earth minerals," 28 Feb. 2018 Electric motors, whether AC or DC, work by causing a magnetic field in the rotating part (rotor) to interact with a magnetic field in the stationary part (stator) of the machine. The Economist, "Do electric cars dream of software fixes?," 22 Apr. 2018 When wire windings in the stator are electrified, the magnetic attraction causes the rotor to rotate. Megan Geuss, Ars Technica, "Toyota’s new magnet won’t depend on some key rare-earth minerals," 28 Feb. 2018 Whatever the mechanism, all electric motors, whether their input current is AC or DC, require an alternating current in their stator windings to make their rotors spin. The Economist, "Do electric cars dream of software fixes?," 22 Apr. 2018 By contrast, induction motors (which are much more common) use no magnets and rely on current flowing through the stator windings to induce a magnetic field, which leads to the rotation of the rotor. Megan Geuss, Ars Technica, "Toyota’s new magnet won’t depend on some key rare-earth minerals," 28 Feb. 2018 Several such coils form the rotor, which is the part of the motor that turns, and which sits inside the stator, which does not. The Economist, "Let’s twist againAs electric motors improve, more things are being electrified," 14 Sep. 2017 That turns them into an electromagnet, generating a magnetic field which pushes against an existing field generated by a second set of permanent magnets inside the stator. The Economist, "Let’s twist againAs electric motors improve, more things are being electrified," 14 Sep. 2017
