Properties of Iron

    Dec 13, 2002 · A property of the iron family for which there is no substitute at an equivalent cost is that they can be induced to provide a strong magnetic field with only small excitation by an electric current. It is a very remarkable property, so an effort will be made to explain how it arises, and how it is used.

    Magnetic Saturation: What is it? | Electrical4U

    Jul 19, 2020 · It is well known to us that iron has very little reluctance. It is much smaller than reluctance of air. But above statement is only true when magnetic flux density is an iron core is less than specific limit. This limit may be from 1.6 to 1.8 Tesla depending upon the particular magnetic steel or iron .

    Why Does a Magnet Attract Iron? | Sciencing

    Most people know that iron is attracted to magnets, while other metals like gold and silver are not. Yet few people can explain exactly why iron has this magical relationship with magnetism. To arrive at the answer, you need to get down to the atomic level and examine the magnetic nature of an atom's electrons.

    In this table the remanent flux density is the retained magnetic field B, and the SI unit for B is the Tesla (T). 1 Tesla = 10,000 gauss. The "coercive force" is the applied reverse magnetic field strength H required to force the net magnetic field back to zero after magnetization. The SI unit for H is A/m, and 1 A/m = 0.01257 oersteds.

    Magnetic Properties: Magnetic properties refer to the metal and alloys such as iron, steel and associated alloying elements such as cobalt and Nickel. All other materials are non-magnetic. Metals and alloys are classified as either hard or soft. Hard magnetic materials retail magnetism after the initial magnetism has been removed.
