Exploring the Magnetic Field of a Slinky
... 14. Once you get a good display of current on the bottom, and induced emf on the top, make an accurate sketch of the scope display. Make sure to write down all relevant parameters such as the time scale and the voltage scales of both channels. Also record the area of the loop and the number of turn ...

5G50.52 Energy Storage with Superconductors
... It was found in 1986 that ceramics, from a class of materials called perovskites, exhibit superconductivity at much higher temperatures. These temperatures can sometimes reach as high as 90 K or even 140 K. These perovskite materials are classified as high-temperature superconductors, whereas those ...

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.
