NATURAL MAGNETS

GENERAL RESULTS ON MAGNETIC FIELD|NATURE OF MAGNETIC FIELD| SIMILARITY BETWEEN ELECTRIC AND MAGNETIC DIPOLE MOMENT

Natural Magnet is known as

The hybridization and magnetic nature of [Mn(CN)_6]^(4-) and [Fe(CN)_6]^(3-) respectively are

The coordination number of Ni^(2+) is 4 NiCI_(2) + KCN (excess)rarr A (cyano complex) Predict the magnetic nature of A and B .

Hybridisation of Mn in [Mn(CN)_6]^(4-) & magnetic nature of [Fe(CN)_6]^(3-) is respectively

Assertion:- Magnetism and superconductivity are natural enemies. Reason:- Macroscopic magnetic properties depend on electrons that are lined up parallel to one another, while superconductivity requries pairs of electrons with their spins in oppsoite directions.
