Is Aluminum Magnetic? The short answer is that under normal circumstances, aluminum is not magnetic. The Nature of Magnetism To understand why certain materials are magnetic and others are not, we need to explore the atomic structure. Atoms consist of protons, neutrons, and electrons. Electrons orbit the nucleus (made of protons and neutrons) in shells and have properties including mass, charge, and spin. The electron spin contributes to a material’s magnetic properties.

Neodymium magnets, noted for their exceptional strength and diverse applications, command a premium in the market.  In this article, we explore the intricate economic and technical factors contributing to the high cost of neodymium magnets, shedding light on the complexities that underpin their pricing. Neodymium Production and Global Supply Dynamics The production of neodymium magnets starts with the extraction of neodymium, a rare-earth element. A significant portion of global neodymium production is concentrated in a few countries, with China playing a dominant role. The geopolitical a ..read more

Magnetic anisotropy in materials is influenced by several factors, each playing a role in determining the preferred direction of magnetization. Here are some key factors that influence magnetic anisotropy. Crystal Structure The arrangement of atoms in the crystal lattice of a material is a fundamental factor. Some crystal structures exhibit a natural alignment that favors certain directions for magnetization, contributing to magnetic anisotropy. Image Source: Wikipedia Crystal Symmetry Effects on Magnetic Anisotropy The symmetry of the crystal lattice affects magnetic anisotropy. Symmetric cr ..read more

Magnetic field lines, meandering through space, are the key to understanding the behavior of magnets and the interactions between magnetic fields. Defining Magnetic Field Lines They are a conceptual tool used to visualize and represent the influence of a magnetic field in a given space. When a magnetic field is present, it exerts a force on other magnetic materials and charged particles within its influence. To make sense of this complex interplay of forces, scientists have devised a visual aid – the magnetic field lines. These lines are imaginary curves that illustrate the direction a hypothe ..read more

The magnetic force has been discovered and explored over centuries. This invisible yet powerful phenomenon plays a fundamental role in shaping the world around us. From guiding compass needles to influencing the behavior of charged particles, it is a fascinating aspect of the universe that permeates various aspects of our daily lives. Understanding the Basics of Magnetic Force At its core, magnetic force is a fundamental interaction between electrically charged particles, specifically electrons. It is a force that acts at a distance, without any physical contact between the objects involved. T ..read more

Magnetic flux density, often denoted as B, plays a fundamental role in understanding the behavior of magnetic fields. It is a key concept used to describe the strength and distribution of magnetic fields around magnets and electric currents. The Basics of Magnetism Magnetism is a phenomenon associated with the alignment of atomic or molecular magnetic dipoles within a material. These dipoles generate a magnetic field, creating two distinct poles – north and south – which exert attractive or repulsive forces on other magnetic materials. Magnetic fields are characterized by their strength and di ..read more

Can you tell us the highest grade of material we can produce for multipolar orientation magnets? Currently, the highest-grade material we use to manufacture polar-anisotropic ring magnets are N45 for UH and N48 for SH. The reason that we can’t push higher is because this type of magnet is not suitable for grain boundary diffusion (GBD). How many pole pairs are you able to manufacture?    4-pole designs are commonly used for high-speed applications, while for high-torque applications, we have successfully produced 28-pole designs for OD ranging from 32 to 35 mm.&nb ..read more

An increase in unsprung weight is a significant hurdle to the development of in-wheel motors. This article will discuss the issue and proposes possible solutions. To understand this article better, let’s start with two fundamental concepts. What Is an In-wheel Motor? An in-wheel motor, as suggested by the name, is a motor located inside the wheels. Its most critical feature is that it combines the car’s power system, transmission system, and braking system, with the motor driving the wheels directly, bypassing any mechanical structures.

Hub motors could be driven by internal rotor motors or external rotor motors. Installed within the wheel, the greatest advantage of the hub motor is that it combines the power system, transmission system, and braking system into one unit. Moreover, electric vehicles using this motor have simpler chassis structures and high transmission efficiency. Depending on whether a reduction mechanism is installed; hub motors can be split into two categories: reduction drive and direct drive. Internal Rotor Motor Drive Reduction drive, also known as internal rotor motor drive, employs a high-speed interna ..read more

In recent years, magnet fishing has become a popular hobby, attracting more and more people to uncover hidden treasures from the underwater. The right magnets for magnet fishing are pivotal to the success of your underwater expeditions. In this comprehensive guide, we will explore the world of magnets specifically designed for magnet fishing. How Strong of Magnets for Magnet Fishing The pulling force of a magnet, measured in kilograms or pounds, is a critical factor. For beginners, a magnet with a pulling force between 200 and 500 pounds (90 to 227 kilograms) is often a good starting point. Mo ..read more
