Difficulty: EasyMagnetism Fundamentals

Which of the following materials is classified as a ferromagnetic substance that is strongly attracted to a magnetic field?

  1. A
    Copper
  2. NickelAnswer
  3. C
    Aluminum
  4. D
    Mica

Answer

Nickel is a ferromagnetic material that is strongly attracted to a magnetic field.
Ferromagnetic materials such as iron, cobalt, and nickel have permanent atomic magnetic dipoles that align easily with an external magnetic field, creating strong magnetic attraction.

Step-by-Step Solution

1
Identify the characteristic properties of ferromagnetic materials.
Ferromagnetic substances contain atomic magnetic domains that readily align with an external field, resulting in strong magnetic attraction.
Ferromagnetism is the basic mechanism by which certain materials form permanent magnets or are strongly attracted to magnets.
2
Evaluate the listed materials to identify the ferromagnetic element.
The primary ferromagnetic elements at room temperature are iron, cobalt, and nickel.
Common conductors like copper and aluminum, as well as insulators like mica, do not exhibit ferromagnetism.
