What is Remanence?

Ever wondered why a magnet stays magnetized long after it’s removed from a magnetic field? That’s remanence at work.

Remanence, or residual magnetization (Br), is the level of magnetism a permanent magnet retains after the external magnetic field is removed.

What Is Permanent Magnet?

Magnets are all around us, but have you ever stopped to think about what makes a magnet “permanent”? Let’s break it down.

A permanent magnet is made from a material that has been magnetized and can hold its magnetic field without needing electricity or another power source.

Magnets play […]

Anisotropic Magnet vs Isotropic Magnet?

Have you ever wondered why some magnets are stronger in one direction than others? Let’s dive into anisotropic and isotropic magnets.

Anisotropic magnets are designed for strength in a single direction, while isotropic magnets offer flexibility but with lower magnetic performance.

Do magnets work in space?

Space may be vast and empty, but did you know magnets don’t need air, gravity, or even contact to do their job?

Magnets work perfectly in space because magnetic fields are not affected by gravity or air. They remain stable and effective even in a vacuum.

What is ferrite?

Ferrite sounds like something from a chemistry lab. But in fact, it’s a key part of many electronics you use every day.

Ferrite is a magnetic ceramic material made from iron oxide and other metals. It offers high resistivity and low eddy current loss, making it […]

What is a Neodymium Magnet (NdFeB)?

Looking for the strongest permanent magnet in the world? Neodymium magnets might be the answer you didn’t know you needed.

Neodymium magnets are rare-earth magnets made from neodymium, iron, and boron. They have the highest magnetic strength of all permanent magnets.

The Strongest Permanent Magnet – Neodymium Magnet

Magnets are everywhere, but few people know which one truly leads the pack in strength.

Neodymium magnets are the strongest permanent magnets available today, outperforming all other types in both magnetic strength and energy density.

How Accurate Is a Magnet Pull Force Calculator?

Magnet strength can be surprising. But how do we measure it without expensive lab tools?

A magnet pull force calculator gives a fast, theoretical estimate of how much weight a magnet can hold under ideal conditions.

A Quick Guide to Magnets

Magnets are everywhere—from fridge doors to wind turbines—but what are they really made of, and why do some metals stick while others don’t?

Magnets are made of materials that can produce a magnetic field, usually metals like iron, nickel, or cobalt, or alloys that include these elements. […]
