Question

if the random. magnetic domains of a substance cannot be organised is One Direction ,
the substance is ferromagnetic true or false​

Answer 1

Answer:

false because they are in one direction only

Answer 2

Ferromagnetic substances

Explanation:

• Ferromagnetic substances are strongly magnetized in an external field in a same direction.
• Examples of ferromagnetic substances are cobalt, iron and nickel.
• On the basis of Domain theory, a ferromagnetic substance contains a large number of small regions called domains, which is an extremely small region containing a large number of atomic magnets aligned in the same direction not in opposite direction.
• In presence of a magnetic field, domains of ferromagnetic substance permanently aligned due to a strong interaction which is known as exchange coupling.
• Ferromagnetic substances do not lose their magnetism even when external magnetic field is removed.

Given statement is false that the substance is ferromagnetic if the random magnetic domains is arranged in one direction.
