How are the elementary magnets aligned in the magnet in figure on the right? Hint: Justify your answer for the 2nd mark

Answer

Alignment of Elementary Magnets in a Magnet

How Elementary Magnets Align Inside a Magnet

🔹 What Are Elementary Magnets?

Elementary magnets, also known as magnetic domains, are microscopic magnetic regions within a material. Each domain acts like a tiny magnet with its own north and south poles.

🔸 How Are They Aligned in a Magnetized Object?

In a magnetized object, these elementary magnets are aligned in the same direction:

  • All north poles point in one direction.
  • All south poles point in the opposite direction.
  • This results in their magnetic fields combining to create a stronger, unified magnetic field.

This alignment is the reason why such a magnet can attract objects like paperclips.

🔸 Why Is Alignment Important?

If the domains were oriented randomly:

  • Their individual magnetic fields would cancel out.
  • The material would not show any magnetism.

Proper alignment leads to visible magnetic behavior and the ability to attract other objects.

⚠️ Note: The magnet in the figure attracts paperclips due to the aligned elementary magnets generating a strong magnetic field.
