Magnetization and Magnetic Intensity We have all played with magnets as children. Some of us even play with them now! But, what makes them ‘magnetic’? Why don’t all the materials and substances possess a magnetic field? Have you ever wondered about it? In this chapter, we will cover the topics of magnetization and magnetic intensity. [...]
Factors Affecting Suction Force of Permanent Magnets Many customers who came to inquire about the magnet’s attraction asked the most about how many Gauss can attract, or send a specification to ask how much it can attract. This is introduced in previous articles. If you are interested, you can click to understand. Today’s main Let’s [...]
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 [...]
Here's the Actual Difference Between Paramagnetism and Diamagnetism Paramagnetism and diamagnetism are two distinct types of magnetic properties exhibited by the different elements in nature. Here, we shall learn more about each of them, and find out how they differ from one another. Levitation! The Radboud University Nijmegen, the Netherlands, conducted experiments where water and [...]
TMR Sensor Magnets TMR sensor is an epoch-making magnetoresistance effect sensor which has been applied to industrial application in recent years. TMR sensor has a much higher resistance change rate compared to AMR and GMR sensor, thus obtained many merits include low cost and power consumption, high response frequency and sensitivity. SDM has also collected [...]
Tile Magnets Magnetization Process First, the reversible displacement of the domain wall When the external magnetic field is small, for the magnetic domain with the same or less external magnetic field with the same direction of spontaneous magnetization, this magnetic domain will expand due to the advantage of low magnetostatic energy; on the contrary, the [...]
Measuring Permanent Magnets Properties with Vibrating Sample Magnetometer Vibrating Sample Magnetometers (VSMs) are the most commonly employed tool for properties measurement of permanent magnet materials. They can be applied to magnet powder, thin films, anisotropic materials, magnetic recording materials, single crystals and liquid, etc.. They also allow for a broad temperature range from 4 K [...]
Rare Earth Magnet Magnetization The magnetization of a magnetized material is the local value of its magnetic moment per unit volume, usually denoted M, with units A/m. It is a vector field, rather than just a vector (like the magnetic moment), because different areas in a magnet can be magnetized with different directions and strengths [...]
