1 What Is Energy?
... All matter is made of particles that are always in random motion. Because the particles are in motion, they have kinetic energy. Thermal energy is all of the kinetic energy due to random motion of the particles that make up an object. As you can see in Figure 5, particles move faster at higher tempe ...

... The losses in an AMB are mainly due to resistive heating in the coils of the electromagnets and eddy-currents in the core and target material [12]. A large part of these losses are due to the bias current for linearization, which can not be removed completely, since this not only would destroy linea ...
