Magnetite an overview ScienceDirect Topics

Magnetite in the brain often occurs as leftover of the iron metabolism, with an increased amount along with inflammation, degeneration or neoplasmic processes. The central nervous system in vertebrates is no sensory organ and therefore cannot monitor parameters of the geomagnetic field. Likewise, magnetite in different organ systems is rather a

Magnetic Classification of Materials Types and Uses

To study the magnetic properties of magnetic materials, we generally keep the material in a uniform magnetic field, and then the magnetic field is varied. Based on their behaviour, the magnetic materials can be classified into three major types: Diamagnetic Materials:

Classification of Magnetic Materials Types of Magnetic

Jan 05, 2016 Magnetic dipoles in these materials are arranged into domains where the arrangements of individual magnetic dipoles are essentially perfect that can produce strong magnetic fields. Normally, these domains are usually randomly arranged and thus the magnetic field of each domain is cancelled by another and the entire material does not show any
