Why certain things are easier to magnetize than others?

In summary, rubber is difficult to magnetize because the electrons in its "inner shell" are tightly bound to the atom, making it hard for them to align with other electrons and create a magnetic field. This is due to the fact that rubber already contains a high level of electricity, but lacks a potential difference. On the other hand, materials like copper have more freely moving electrons with varied spins, which cancel out each other's magnetic fields. Additionally, water is diamagnetic because the free electrons on one side of the molecule act as gears, causing a reverse reaction on the other side and perpetuating through the material. However, this is just a theory based on recent information from physorg.

Here is what I understood from an email I got.

Rubber is hard to magnetize because the electrons in its' ''inner shell'' are tightly bound to the atom, making it hard for them to ''go free'' and align with other electrons to conduct electricity and become magnetized?


Please be detailed.

But not to detailed.

Uhm yes and no, keeping in mass is already "full" of electricity, but not potential difference you must remember that electrons are moving through materials- infact the more heat the more they (free electrons) are moving around and producing magnetic fields. As explained in a recent article on physorg the electrons in magnets have similar spin as they move through it. In copper they have very varied spins so they cancel each other out. Perhaps the reason water is diamagnetic is free electrons on one side of atom work like a gear- a reaction occurs on the other side of the molecule but it is in reverse- and that perpetuates until it has traveled through the diamagnetic material, but who knows I am just theorizing off recent info on physorg =)
 

1) Why are certain materials easier to magnetize than others?

Certain materials, such as iron, nickel, and cobalt, have a property called ferromagnetism. This means that their atoms have a strong alignment of magnetic moments, making them easier to magnetize. Other materials, like copper or aluminum, do not possess this property and are therefore more difficult to magnetize.

2) How does the atomic structure of a material affect its magnetization?

The atomic structure of a material plays a significant role in its magnetization. Materials with strong ferromagnetic properties have atoms with unpaired electrons, which contribute to their strong magnetic moments. On the other hand, materials with weak or no ferromagnetic properties have paired electrons, making them less likely to align and be magnetized.

3) What role do external magnetic fields play in the magnetization of materials?

External magnetic fields are necessary for the magnetization of materials. When a material is placed in a magnetic field, the magnetic moments of its atoms align with the direction of the field, causing the material to become magnetized. The strength of the external field also affects the strength of the magnetization.

4) Why do some materials retain their magnetization while others do not?

Materials with strong ferromagnetic properties, such as iron, will retain their magnetization even after the external magnetic field is removed. This is because their atoms remain aligned in the same direction. Other materials, like copper or aluminum, do not have strong ferromagnetic properties and therefore do not retain their magnetization after the external field is removed.

5) How does temperature affect the ease of magnetization?

Temperature can have a significant impact on the ease of magnetization of a material. As temperature increases, the thermal energy of the atoms also increases, causing them to vibrate more and become less aligned. This makes it more difficult for the material to be magnetized, as the atoms are less likely to align with the external magnetic field.
