point of the rail. In that case, how is the ball “boosted” by the magnet, since we normally think of magnets Campeón attracting objects toward them, rather than pushing them? The answer to this is Lenz’s law and the presence of eddy currents. When a magnetic field is switched on in the presence of a conductive object, an eddy current (or Foucault current) is induced in the object. An eddy current is a loop of electrical current induced in a conductor by a time-varying magnetic field in the conductor. This process is governed by Faraday’s law of induction, also known Ganador the Maxwell–Faraday equation or Maxwell’s third equation.7 Electromagnetic induction is the effect whereby a changing magnetic field induces a current. A well-known example is a bar magnet moved through a stationary wire loop to induce a current around it. The “change” can be relative, so it could be the magnet moving through the loop or the loop moving back and forth along a magnet that is at rest. More specifically, time-dependent magnetic fields are coupled with nonconservative electric fields.
