Write the type of magnetism observed when the magnetic moments are oppositely aligned and cancel out each other.
Explain the following with suitable examples:
Antiferromagnetism
Example of ferromagnetic substance is ____________.
All those atoms or molecules which have an odd number of electrons are
When heated to high temperature, ferromagnetic substance changes to ____________.
Assertion: On heating ferromagnetic or ferrimagnetic substances, they become paramagnetic.
Reason: The electrons change their spin on heating.
The value of magnetic moment is zero in the case of antiferromagnetic substances because the domains:
(i) get oriented in the direction of the applied magnetic field.
(ii) get oriented opposite to the direction of the applied magnetic field.
(iii) are oppositely oriented with respect to each other without the application of magnetic field.
(iv) cancel out each other’s magnetic moment.
Which one of the following homo-diatomic molecule is paramagnetic?
Given below are two statements labelled as Assertion (A) and Reason (R).
Assertion: Magnetic moment values of actinides are lesser than the theoretically predicted values.
Reason: Actinide elements are strongly paramagnetic.
Select the most appropriate answer from the options given below:
The value of aluminium susceptibility is 2.2 × 10-5. The percentage increase in the magnetic field if space within a current carrying toroid is filled with aluminium is `"x"/10^4`. Then the value of x is ______.
