A paramagnetic sample shows a net magnetization of 8 Am–1 when placed in an external magnetic field of 0.6T at a temperature of 4K. When the same sample is placed in an external magnetic field of 0.2 T at a temperature of 16K, the magnetization will be
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 ![]()
