It forms in igneous and metamorphic rocks and has been used for centuries, even by ancient navigators in the form of lodestones.<\/p>\n<p>Magnetite is magnetic due to its unique crystal structure. It has both Fe\u00b2\u207a and Fe\u00b3\u207a ions. The unpaired electrons in these iron ions align in a way that creates a spontaneous magnetic field.<\/p>\n<p>Not all iron-containing rocks are magnetic, though. The crystal structure and atomic arrangement are just as important as the elements themselves.<\/p>\n<table>\n<thead>\n<tr>\n<th>Material<\/th>\n<th>Magnetic?<\/th>\n<th>Natural?<\/th>\n<th>Notes<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td>Magnetite<\/td>\n<td>Yes<\/td>\n<td>Yes<\/td>\n<td>Naturally magnetic iron oxide<\/td>\n<\/tr>\n<tr>\n<td>Hematite<\/td>\n<td>No<\/td>\n<td>Yes<\/td>\n<td>Contains iron, but not magnetic<\/td>\n<\/tr>\n<tr>\n<td>Iron (metal)<\/td>\n<td>Yes<\/td>\n<td>No<\/td>\n<td>Becomes magnetic when processed<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<p>Understanding natural magnets helps us appreciate how industrial magnets are designed to replicate and enhance these natural properties.<\/p>\n<h2><\/h2>\n<h2>What are the ingredients in a magnet?<\/h2>\n<p>Not all magnets are made the same.

The choice of materials depends on the magnet\u2019s use.<\/strong><\/p>\n<h3><\/h3>\n<h3>Comparing common magnet types and materials<\/h3>\n<p>There are many types of magnets, each with different &#8220;ingredients&#8221; or base materials.
