2) Materials that can be made into permanent magnets are a. paramagnetic. b. diamagnetic. c. ferromagnetic. d. none of the above
A permanent magnet is an object made from a material that is magnetized and creates its own persistent magnetic field. An everyday example is a refrigerator magnet used to hold notes on a refrigerator door. Materials that can be magnetized, which are also the ones that are strongly attracted to a magnet, are called ferromagnetic (or ferrimagnetic). These include iron, nickel, cobalt, some alloys of rare earth metals, and some naturally occurring minerals such as lodestone. Although ferromagnetic (and ferrimagnetic) materials are the only ones attracted to a magnet strongly enough to be commonly considered magnetic, all other substances respond weakly to a magnetic field, by one of several other types of magnetism
C
Permanent magnets are made from "hard" ferromagnetic materials such
as alnico and ferrite.

The magnetic properties of matter can be categorized according to three types: diamagnetic, ferromagnetic, and paramagnetic materials. For each property shown below, categorize it according to one of these three types. Why is this wrong? The magnetic properties of matter can be categorized according to three types: diamagnetic, ferromagnetic, and paramagnetic materials. For each property shown below, categorize it according to one of these three types. Diamagnetic Ferromagnetic Slightly attracted to magnetic fields Strongly positive magnetic susceptibilty Contains magnetic domains...

Liquid oxygen collected into a test tube is found to be a. nonmagnetic. b. ferromagnetic. c. paramagnetic. d. diamagnetic.
Magnetic properties (diamagnetic or paramagnetic behavior) of different chemicals are predicted b... Magnetic properties (diamagnetic or paramagnetic behavior) of different chemicals are predicted based on the absence of presence of unpaired electrons. For diatomic covalent species, the MO theory should be used. For polyatomic molecules and molecular ions, Lewis structures should be used. For atomic ions and ionic solids that include them, electronic configurations should be used. Label each of the following species as diamagnetic or paramagnetic and indicate if...
