Question

How are the atoms found in nonmagnetic materials different than the atoms found in magnetic materials?

1 The atoms of nonmagnetic materials are positively charged
2 The atoms of nonmagnetic materials all face the same direction
3 The atoms of nonmagnetic materials are not grouped in magnetic domains
4 The atoms of nonmagnetic materials are grouped in magnetic domains.

Answer 1

In substances such as iron, cobalt, and nickel, most of the electrons spin in the same direction. This makes the atoms in these substances strongly magnetic—but they are not yet magnets. ... The force generated by the aligned atoms creates a magnetic field. The piece of iron has become a magnet.

Answer 2

The atoms of nonmagnetic materials are positively charged is the correct answer.

Explanation:

Magnetic materials are those that, when placed near a magnet, attract one other. When positioned near a magnet, non-magnetic materials will not experience any magnetic force.

The atoms of nonmagnetic materials are positively charged :

• Positive and negative poles are found in all magnets. To construct a negative charge magnet, you'll need to start with a simple magnet.

The atoms of nonmagnetic materials all face the same direction :

• A permanent magnet is just a ferromagnetic object with all of its domains aligned in the same direction.

The atoms of nonmagnetic materials are not grouped in magnetic domains :

• Magnetic domains develop in magnetically ordered materials, where the dipoles spontaneously align due to the exchange contact.

The atoms of nonmagnetic materials are grouped in magnetic domains :  

• Arrangement of electrons in the atoms of the substance is the most fundamental factor. Then there's the next level.
