Question
What is ferromagnetism?
Advertisements
Solution
- Ferromagnetism is a property of certain materials in which the atoms have unpaired electrons whose spins align parallel to each other, resulting in a strong, permanent magnetic moment.
- The substances that can be permanently magnetised even in the absence of a magnetic field are called ferromagnetic substances, and the mechanism is called ferromagnetism.
- Some examples of ferromagnetic substances are iron, cobalt, nickel, gadolinium, and CrO2.
