3 Ways to Make a Magnet - wikiHow

 · How to Make a Magnet. In this Article: Article Summary Making a Paperclip Magnet Making an Electromagnet Making a Compass Magnet Community Q&A Magnets are made by exposing ferromagnetic metals like iron and nickel to magnetic fields. When these metals are heated to a certain temperature, they become permanently magnetized.

Magnet Basics - K&J Magnetics, Inc.

A permanent magnet is an object that produces a magnetic field around itself. It is this field that enables them to stick to each other and to some types of metal. Specifically, they stick to ferromagnetic materials like iron and things that contain iron, such as steel. This includes everything from your car's steel body to your refrigerator door.

Tuning the Magnetic Properties of Nanoparticles

 · In the case of large, ferromagnetic nanoparticles, heating occurs due to hysteresis losses and Brownian relaxation. For small nanoparticles in the single-domain or superparamagnetic range, hysteresis losses are negligible or absent, and heating arises from Neel and Brownian relaxation.
