A paramagnetic sa

Answer :

Given:


The magnetic field in the sample kept in is and the magnetic field in the sample kept in is . The current flowing in the sample at is . To find the value of current flowing in the sample kept in is denoted by.


Formula used:


To find the value of, we use the relation of Curie’s Law which states that magnetic field is directly proportional to the magnetization.



where


M is the magnetization of the sample, B is the magnetic field, t is the temperature of the samples kept and C is the Curie Constant.


Explanation:


Paramagnetic samples or materials are those that remain magnetized as long as they are present in a magnetic field other than that they possess no magnetic ability.


Now to find the value of current flowing in the sample kept in 16K is




Therefore, the value of the current flowing in the second sample is
