Magnetic fields in materials are due to the alignment of magnetic dipoles within their atoms. Ferromagnetic materials, like iron, have magnetic domains where magnetic dipoles are rigidly aligned, allowing these materials to become magnets. Diamagnetic materials, on the other hand, only display magnetic fields when an external magnetic field is applied.
Magnetic fields in materials are caused by the alignment of magnetic dipoles within the atoms of the materials. In the case of ferromagnetic materials like iron, cobalt, nickel, and gadolinium, tiny regions called magnetic domains contain magnetic dipoles rigidly aligned in the same direction. The coupling among these atoms is so strong that even thermal agitation cannot break it, creating a net dipole moment for the entire domain. For this reason, ferromagnetic materials can be induced to become magnetic or made into permanent magnets.
On the other hand, diamagnetic materials have no permanent magnetic dipole moments. When a magnetic field is applied to these materials, it induces a magnetic dipole in an atom which points opposite to the applied field. This induced dipole thus produces a magnetic field that is also directed opposite to the applied field.
Lastly, all matter has a property called a magnetic dipole moment. A magnetic field can be caused by a magnet, a moving electrically charged object or by magnetic dipoles or combinations of dipoles. However, magnetic fields observed in nature are not produced by single poles.

Answer:
ethanol is already at the ethanol's boiling point: (0.826 kJ/g) x (70.05 g) = 57.8613 kJ = 5.79 x 10^4 J.
Missing: 45.65 | Must include: 45.65
Explanation:
Answer:
Explanation:
Supposing the temperature of the ethanol is already at the ethanol's boiling point:
(0.826 kJ/g) x (70.05 g) = 57.8613 kJ = 5.79 x 10^4 J
Answer:
FE is iron so its two irons and O is oxygen and its 3 oxygen
is that what you want?
