A superconductor is a material that, below a certain critical temperature, has the ability to conduct electricity without any resistance. In addition, it exhibits the phenomenon of perfect diamagnetism, which means it expels all magnetic fields from within the material (known as the Meissner effect).
Therefore, a superconductor exhibits diamagnetism, which is a characteristic of materials that weakly repel magnetic fields.
Final Answer: Dia magnetism
In the given circuit, the electric currents through $15\, \Omega$ and $6 \, \Omega$ respectively are

Two bar magnets A and B are identical and arranged as shown. Their lengths are negligible compared to the separation between them. A magnetic needle placed between the magnets at point P gets deflected through an angle \( \theta \) under their influence. The ratio of distances \( d_1 \) and \( d_2 \) is:
