Out of given paramagnetic substance (Calcium, Chromium, Oxygen and Tungsten) which substance has maximum susceptibility?
A paramagnetic liquid is taken in a U-tube and arranged so that one of its limbs is kept between pole pieces of the magnet. The liquid level in the limb is
The magnetic susceptibility of a paramagnetic material at $-73^0$ is $0.0075$, its value at $-173^0$C will be
Assertion : Paramagnetic substances get weakly attracted to a magnet.
Reason : They have tendency to move from a region of strong magnetic field to weak magnetic field
Consider the following statements I and II.
(I) Paramagnetism is explained by domain theory
(II) Susceptibility of a diamagnetic substance is independent of temperature.
Identify the correct choice from the following.
Assertion(A) : Earth's magnetic field inside a closed iron box is less as compared to the outside.
Reason(R) : The magnetic permeability of iron is low.
The meniscus of a liquid contained in one of the limbs of a narrow U-tube is held electromagnet with the meniscus in line with the field. The liquid is seen to rise. This indicates that the liquid is
Metals getting magnetised by orientation of atomic magnetic moments in external magnetic field are called
The purpose of soft iron cylinder between the pole pieces of the horse-shoe magnet in a moving coil galvanometer is
A bar magnet has been cut equally lengthwise and widthwise to give four equal pieces. The pole strength of each piece as compared to the pole strength of original bar magnet is :
Magnetically aligned atoms in a magnetic material forms a cluster. The cluster is called a:
