Ferromagnetic ferrimagnetic and antiferromagnetic substances | 1Minute Chemistry | SM Sir |#SHORTS |

Ferrimagnetic substance show better magnetism than antiferromagnetic Substances. Why ?

Define : (1) ferromagnetic (2) paramagnetic (3) diamagnetic substances

(a) Give two differences between ferromagnetic and anti-ferromagnetic substances. (b) Tungsten crystallizes in body centred cubic lattice. Calculate the number of unit cells in 1.5 g of tungsten. (At mass of tungsten = 184 u)

What is the difference between anti-ferromagnetic and ferrimagnetic substances ? What is the cause of the difference ?

Needles N_(1) , N_(2), and N_(3) are made of a ferromagnetic, a paramagnetic and a diamagnetic substance respectively . A magnet when brought close to them will

With the help of electron spins, clearly distinguish between Ferromagnetic, Antiferromagnetic and Ferrimagnetic substances.

Give reasons : (i) In stoichiometric dfects. NaCl exhibits Schottky defect and not Frenkel defect. (iii) Ferrimagnetic substances show better magnetism than antiferromagnetic substances.
