After a long discussion on the magnetic states of matter, Student a arrived at the conclusion that ferromagnetic materials have greater magnetic moments than ferrimagnetic materials. Student b held firm to the opposite scenario. Who is correct?
Accepted Answer
Student B is correct. While both ferromagnetic and ferrimagnetic materials exhibit strong magnetic moments, ferrimagnetic materials generally have higher magnetic moments than ferromagnetic materials. This is because in ferrimagnetic materials, the magnetic moments of the different ions within the material align in opposite directions, but the magnitude of the moments of one ion is larger than the other, leading to a net magnetic moment. In ferromagnetic materials, the magnetic moments of all the ions align in the same direction, contributing to a lower overall magnetic moment.
