Step 1: Run skewer through two corks as shown
... A machine that converts electrical energy into mechanical energy is a motor. Current flowing in a loop of wire produces a magnetic field. Since opposite magnetic poles attract (and like poles repel), the coil will spin until it is aligned with its own north pole adjacent to the south pole of the per ...

1 AC Losses in High Temperature Superconductors under non –Sinusoidal Conditions
... A superconductor has zero resistance only under DC conditions, under AC conditions a changing magnetic field (either self generated or externally applied) acting on the material interacts with transport and leads to energy dissipation. The subject of AC losses in superconductors may be considered un ...

Magnetism
Magnetism is a class of physical phenomena that are mediated by magnetic fields. Electric currents and the magnetic moments of elementary particles give rise to a magnetic field, which acts on other currents and magnetic moments. Every material is influenced to some extent by a magnetic field. The most familiar effect is on permanent magnets, which have persistent magnetic moments caused by ferromagnetism. Most materials do not have permanent moments. Some are attracted to a magnetic field (paramagnetism); others are repulsed by a magnetic field (diamagnetism); others have a more complex relationship with an applied magnetic field (spin glass behavior and antiferromagnetism). Substances that are negligibly affected by magnetic fields are known as non-magnetic substances. These include copper, aluminium, gases, and plastic. Pure oxygen exhibits magnetic properties when cooled to a liquid state.The magnetic state (or magnetic phase) of a material depends on temperature and other variables such as pressure and the applied magnetic field. A material may exhibit more than one form of magnetism as these variables change.
