Why does the automotive industry need magnetic measurements? The fact that magnets are being used more and more in the automotive industry is no longer a secret, as technology has continued to develop. In the beginning, ferrite magnets were used frequently. But now these magnets are more and more replaced by neodymium magnets, because they [...]
Magnetic Measurements for Automotive Industry The fact that magnets are being used more and more in the automotive industry is no longer a secret, as technology has continued to develop. In the beginning, ferrite magnets were used frequently. But now these magnets are more and more replaced by neodymium magnets, because they offer the advantage [...]
Magnetization Dynamics 1 Introduction Magnetization dynamics, where one investigates the time-dependent motion of the magnetization rather than its equilibrium behavior, are fundamental to the properties of magnetic materials. It is worthwhile remembering that the concept of spin waves was introduced by Bloch in 1930 in order to calculate the magnetic contribution to the specific heat [...]
MPCO Can Test the Angular Direction (ϕ, θ) of Magnetization! How well do you need to know your magnets? Using our m-axis testing equipment, magnetic moment, remanence and magnetization direction of magnetic dipoles can be characterized with high precision. The calculation is based on determination of the dipole using an integrated AMR sensor set-up. The [...]

Magnetizing or Magnetization In magnetizing the magnetic domains inside of a magnet are aligned with the magnetizing field. If the magnetizing field strength is high enough, all the domains will be aligned and the magnet is said to be magnetized to saturation. Magnetizing to saturation is usually recommended as only then are the magnetic properties [...]
Magnetic Measurements Magnetic Measurements For measuring of the fundamental magnetic properties of a material (Br, bHc, iHc, BHmax, demagnetisation curve), Hysteresisgraph or BH-tracker is used. A BH-tracker consists of an iron (usually FeCo) yoke to form a closed circuit, electromagnets to create the demagnetizing field and fluxmeters to determine the demagnetizing field and the materials [...]
