Neodymium magnets have replaced alnico and ferrite magnets in many of the myriad applications in modern technology where strong permanent magnets are required, because their greater strength allows the use of smaller, lighter magnets for a given application. Some examples are:     ► Head actuators for computer hard disks     ► Magnetic resonance imaging (MRI)     ► Magnetic guitar pickups     ► Mechanical e-cigarette firing switches     ► Locks for doors     ► Loudspeakers and headphones     ► Magnetic bearings and couplings     ► Benchtop NMR spectrometers     ► Electric motors:          ●  Cordless tools          ●  Servomotors          ●  Lifting and compressor motors          ●  Synchronous motors          ●  Spindle and stepper motors          ●  Electrical power steering          ●  Drive motors for hybrid and electric vehicles.              (Toyota Prius require 1 kilogram (2.2 pounds) of neodymium.)          ●  Actuators
