प्रश्न
Which one of the following would feel attraction when placed in magnetic field: Co2+, Ag+, Ti4+, Zn2+
Advertisements
उत्तर
Co2+ has three unpaired electrons so it would be paramagnetic in nature, hence Co2+ ion would be attracted to magnetic field.

Fe3O4 is ____________.
Which type of substances would make better permanent magnets?
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.
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.
