(A) Super conductors
(B) Insulators
(C) Semi conductors
(D) All

Answer 1

Explanation:

semi conductors .................

Answer 2

Super conductors are the best diamagnetic materials.

Explanation:

• Two of the strongest diamagnetic materials are graphite and bismuth.
• The forces created by diamagnetism are extremely weak, millions of times smaller than the forces between magnets and such common ferromagnetic materials as iron.
• Above the critical temperature (Tc), a superconductor has no notable effect when a magnetic field is applied, as the magnetic field is able to pass through the superconductor unhindered.
• This results in the superconductor having a magnetic susceptibility of -1, meaning it exhibits perfect diamagnetism.
