WebMagnetic Hysteresis. The phenomenon of flux density B lagging behind the magnetizing force H in a magnetic material is known as Magnetic Hysteresis. The word Hysteresis is derived from the Greek word Hysterein means to lag behind. In other words, when the magnetic material is magnetized first in one direction and then in the other direction ... Diamagnetic materials are repelled by a magnetic field; an applied magnetic field creates an induced magnetic field in them in the opposite direction, causing a repulsive force. In contrast, paramagnetic and ferromagnetic materials are attracted by a magnetic field. Diamagnetism is a quantum mechanical effect that occurs in all materials; when it is the only contribution to the magnetism, the material is called diamagnetic. In paramagnetic and ferromagnetic substances, …

WebMost materials can be classified as diamagnetic, paramagnetic, or ferromagnetic. Diamagnetic materials have a weak, negative susceptibility to magnetic fields. Diamagnetic materials are slightly repelled by a magnetic field and do not retain the magnetic properties when the external field is removed. In diamagnetic materials all the … WebHysteresis loops can provide a lot of information about the magnetic nature of a sample. By simple inspection it is clear if the sample is diamagnetic, paramagnetic, superparamagnetic, or ferromagnetic (ferrimagnetic). When actual hysteresis is observed (an opening in the curve) further information about the strength and direction of the ... WebHysteresis: Hysteresis loop (Fig. 1) shows the relation between the magnetization ⃗ or the magnetic induction ⃗ as a function of ⃗ . It is a characteristic property of any ferromagnetic material. The dotted line in Fig. 1 shows that as the applied field is increased the magnetization in the domains grows along the so-called easy fivg fact sheet
