The paramagnetic is at a temperature of 30 °C. The concentration of atoms is 1027 m-3, the magnetic moment of an atom is equal to twice the Bohr magneton. Estimate by how much the number of atoms whose magnetic moments are oriented along the field is greater than the number of atoms whose magnetic moments are oriented against the field if the field induction is 1.2 T. How will the result change if the substance is cooled to the temperature of liquid nitrogen (-195.8 °C)?
