Answer 1

$\huge\bold\red{Answer:-}$

What is paramagnetism?

The property of certain materials that are weakly attracted to magnetic field is termed as paramagnetism.

Materials that display paramagnetism are called paramagnetic.

It was discovered by Micheal Faraday.

What is Curie's law of paramagnetism?

According to the Curie's law for paramagnetic materials, in a paramagnetic material, the magnetization of the material is inversely directly proportional to the magnetic field applied to it.

It will be different in case of heating the as material's magnetization becomes inversely proportional to the temperature.

What is Meissner Effect?

When a material makes the transition from the normal to superconducting state, it actively excludes magnetic fields from its interior; this is called the Meissner effect.

It is the expulsion of magnetic flux when a material becomes superconducting in a magnetic field.

Answer 2

$\huge \underline \bold \red{Answer}$

Q1 ) What is Curie's law of paramagnetism ?

➡ The curie law states that in a paramagnetic material, the material's magnetization is directly proportional to an applied magnetic field. When it is heated, the relation is reversed.

Q2) What is Meissner Effect ?

➡Meissner effect, the expulsion of a magnetic field from the interior of a material that is in the process of becoming a superconductor, that is, losing its resistance to the flow of electrical currents when cooled below a certain temperature, called the transition temperature, usually close to absolute zero.
