A superconductor exhibits perfect
- ferrimagnetism
- ferromagnetism
- paramagnetism
- diamagnetism.
The Correct Option is D
Solution and Explanation
When chilled to a specific critical temperature, superconductors have a resistance equal to zero. Below a certain critical temperature, superconductors exhibit the Meissner phenomenon, in which the superconductor expels all magnetic fields.
Check the attributes of each option in the question to see which one matches the superconductors.
Ferromagnetism: A ferrimagnetic material has atom populations with opposing magnetic moments, the opposing moments are uneven, and a spontaneous magnetization remains.
As a result, the characteristics do not correspond to those of superconductors.
Ferromagnetism is the fundamental process by which some materials produce permanent magnets. Ferromagnetism is the strongest form and is responsible for the frequent occurrence of magnetism found in magnets.
As a result, the characteristics do not correspond to those of superconductors.
Paramagnetism is a kind of magnetism in which some materials are weakly attracted by an externally applied magnetic field, causing magnetic fields to be produced in the direction of the applied magnetic field.
The properties of paramagnetic materials do not correspond to those of superconductors.
Diamagnetism: Diamagnetic materials reject magnetic fields; an applied magnetic field induces an induced magnetic field in them in the opposite direction, resulting in a repulsive force.
As a result, the characteristics of superconductors correspond to the features of diamagnetism.

Current Electricity
Current electricity is defined as the flow of electrons from one section of the circuit to another.
Types of Current Electricity
There are two types of current electricity as follows:
Direct Current
The current electricity whose direction remains the same is known as direct current. Direct current is defined by the constant flow of electrons from a region of high electron density to a region of low electron density. DC is used in many household appliances and applications that involve a battery.
Alternating Current
The current electricity that is bidirectional and keeps changing the direction of the charge flow is known as alternating current. The bi-directionality is caused by a sinusoidally varying current and voltage that reverses directions, creating a periodic back-and-forth motion for the current. The electrical outlets at our homes and industries are supplied with alternating current.
