Electronic circuits have also been built using superconductors and powerful superconducting electromagnets are used in magnetic resonance imaging (MRI). Also, very low electrical-loss components, known as filters, based on ceramic superconductors have been developed for wireless communications.

Why does superconductivity occur in certain materials at low temperature?
Superconductivity is a purely quantum mechanical phenomenon. And as all quantum mechanical effects it disappears at high temperatures and/or large scale. One of ways to see quantum effects is to lower the temperature (in this case it's only way).
Which element has the property of zero resistance?
Several materials have this property at very low temperatures. Some of them are elements, some are compounds. Do some reading on "superconductivity" for more information.
How are the magnets able to have zero resistance?
If you mean zero electrical resistance for an electromagnet, this is possible with superconductivity. This can be achieved for certain materials at fairly low temperatures - typically a few kelvin.
How superconductivity relates to ohm's law?
Ohm's law states that the current flowing through a conductor is directly proportional to the voltage applied across it and inversely proportional to its resistance. Superconductivity is a property observed in certain materials where they exhibit zero electrical resistance below a critical temperature. In superconductors, Ohm's law is not applicable as there is no resistance to impede the flow of current, resulting in the potential for an infinite current to flow in a closed circuit without needing a voltage difference.
What are the maximum temperatures that a radiator can reach?
the superconductivity radiator is a leading technology around the worldmedium in it will be activated while the temperature rises to 35Cthe collision between atom and molecule results in higher temperature about 85C in 3 minutes
Application of superconductivity in mechanical and electrical engineering?
applications of superconductivity
What role does temperature play in superconductivity?
The lower the temperature, the higher the degree of superconductivity.
Which scientist discovered superconductivity?
It was the Dutch physicist Heike Kamerlingh Onnes who discovered superconductivity in 1911.

What are some uses of supercooling?
Superconductivity (reducing electromagnetic resistance (ohms) to nearly zero, which allows minimal energy loss and the ability to be a super-magnet).
