The substances in which atoms cooperate with each
other in such a way so as to exhibit strong magnetic
field are called:​

Answer 1

Answer:

The substance in which atoms cooperate with each other in such a way so as to exhibit strong magnetic field are ferromagnetic substances,

Explanation:

1. Ferromagnetic materials are those that, even in the absence of an external magnetic field, exhibit spontaneous net magnetization at the atomic level.
2. Ferromagnetic materials become strongly magnetised in the field's direction when exposed to an external magnetic field. Ferromagnetic materials are attracted to a magnet very strongly, even after the external magnetising field is withdrawn, these materials will continue to be magnetic for a while.
3. In ferromagnetic materials, the spins of neighbouring atoms do align even in the absence of an external field (through a quantum effect known as exchange coupling), resulting in small (a tenth of a millimetre, or less) neighbourhoods called domains where all the moments are aligned.

Hence the ferromagnetic materials will be the answer.

Answer 2

Answer:

Ferromagnetic substances

Explanation:

• Ferromagnetic materials are those in which each individual atom/molecule/ion has a non zero magnetic moment.
• The atoms of ferromagnetic material have permanent dipole moment present in domains.

• When ferromagnetic materials placed in an external magnetic field, it strongly magnetized In the same direction of magnetic field.

• Ferromagnetic materials produces heavy attraction of magnetic lines of force towards center of the material.

• Ferromagnetic materials are strongly attracted to a magnet.

• Ferromagnetic materials do not lose their magnetism, on removal of external magnetic field. they are permanent magnets.

• Ferromagnetic materials are only solid materials.

         Examples: Iron, nickel, and cobalt, etc.
