Ferromagnetism is the basic mechanism by which certain materials (such as iron) form permanent magnets, or are attracted to magnets. In physics, several different types of magnetism are distinguished. Ferromagnetism (including ferrimagnetism) is the strongest type: it is the only one that typically creates forces strong enough to be felt, and is responsible for the common phenomena of magnetism in magnets encountered in everyday life. Substances respond weakly to magnetic fields with three other types of magnetism, paramagnetism, diamagnetism, and antiferromagnetism, but the forces are usually so weak that they can only be detected by sensitive instruments in a laboratory. An everyday example of ferromagnetism is a refrigerator magnet used to hold notes on a refrigerator door. The attraction between a magnet and ferromagnetic material is "the quality of magnetism first apparent to the ancient world, and to us today".
Permanent magnets (materials that can be magnetized by an external magnetic field and remain magnetized after the external field is removed) are either ferromagnetic or ferrimagnetic, as are other materials that are noticeably attracted to them. Only a few substances are ferromagnetic. The common ones are iron, nickel, cobalt and most of their alloys, some compounds of rare earth metals, and a few naturally-occurring minerals such as lodestone.
Wikipedia (i/ˌwɪkᵻˈpiːdiə/ or
i/ˌwɪkiˈpiːdiə/ WIK-i-PEE-dee-ə) is a free-access, free-content Internet encyclopedia, supported and hosted by the non-profit Wikimedia Foundation. Those who can access the site can edit most of its articles. Wikipedia is ranked among the ten most popular websites, and constitutes the Internet's largest and most popular general reference work.
Jimmy Wales and Larry Sanger launched Wikipedia on January 15, 2001. Sanger coined its name, a portmanteau of wiki and encyclopedia. Initially only in English, Wikipedia quickly became multilingual as it developed similar versions in other languages, which differ in content and in editing practices. The English Wikipedia is now one of 291 Wikipedia editions and is the largest with 5,081,662 articles (having reached 5,000,000 articles in November 2015). There is a grand total, including all Wikipedias, of over 38 million articles in over 250 different languages. As of February 2014, it had 18 billion page views and nearly 500 million unique visitors each month.

Ferromagnetic Meaning
We have discussed here what Ferromagnetic Materials is, in details along with its basic concept.
This video discusses electron spin and the magnetic properties it creates such as diamagnetism, paramagnetism, and ferromagnetism. it also shows how to determine if a substance is diamagnetic vs paramagnetic using paired and unpaired electrons. The examples include the electron configuration of Phosphorus (P) and Neon (Ne).

The attraction of a paramagnetic substance to a strong magnetic field is demonstrated. This is contrasted with the effect of a magnetic field on a ferromagnetic substance.
Ferrofluid is a liquid that reacts to a magnetic field. It's usually made from a mixture of oil and tiny iron particles. Today we're going to look at 4 different demonstrations involving ferrofluid and powerful neodymium magnets. Make sure you are subscribed for more Scientific Tuesdays!

Thorned spikes? This time my 6x2" neodymium magnet meets something unusual, a magnetic fluid. It is called ferrofluid and reacts spectacularly near any magnet, but even better near such a large and powerful magnetic pole surface - even with a surprising shape on the spikes! The ferrofluid and magnetic putty were donated by supermagnete.com for an earlier video.
