Thank you very much for checking this part on scientific English. Here is the last part.

1) The superconductors are also characterized by the so called Meissner-Ochsenfeld Effect. When a superconductor is put in (into) a magnetic field, it produces a magnetic field which opposes it to the first one.
2) The magnetic levitation is based on this particular effect. Thanks to it, we can put a magnet over a superconductor and see how it levitates without any friction between the magnet and the superconductor.
3) This effect is used in Maglev train, which can reach between 300 and 500 km/h. Superconductors are also used in the transport of electric energy. As a matter of fact, thanks to their zero resistivity, they don’t dispel energy as heat through the Joule effect.
4) This important feature allows to make power lines able to transport electric energy without any problem connected with dissipation of energy.
