An example of these subatomic structures would be nuclei or electrons. As electrons spin and orbit a nucleus, they produce a magnetic field.<\/p>\n<p>Now, the direction of the spin and orbit indicate the direction of the field. Pairs of electrons that spin and orbit in opposite directions cancel each other out, creating a net magnetic field of zero.<\/p>\n<p>A <strong>magnetic moment<\/strong> is the strength of a magnetic field. Materials that have an unpaired electron are what we consider to be magnetic. That brings us to <em>three<\/em> different types of material.<\/p>\n<p>The first is a <strong>paramagnetic material<\/strong>, which has a weak attractive force. Then, a <strong>ferromagnetic<\/strong> material, which has a strong attractive force. Then, finally, <strong>diamagnetic<\/strong> materials, which have electrons that are paired.<\/p>\n<p>Now, remember a second ago we said that materials that have an unpaired electron are magnetic. Well, here we&#8217;re calling this diamagnetic. It has magnetic and the word, yet it has paired electrons.<\/p>\n<p>Diamagnetic materials do not typically have a magnetic moment. They typically do not have a magnetic field. However, there are some diamagnetic materials that have a weak magnetic field.<\/p>\n<\/div>\n<\/div>\n\n","protected":false},"excerpt":{"rendered":"<p>How is a Magnetic Field Created? | Physic Review Part 1<\/p>\n","protected":false},"author":1,"featured_media":0,"parent":0,"menu_order":0,"comment_status":"closed","ping_status":"open","template":"","meta":{"footnotes":""},"class_list":{"0":"post-13143","1":"page","2":"type-page","3":"status-publish","5":"page_category-electricity-magnets-and-circuits","6":"page_type-video","7":"page_domain-science"},"aioseo_notices":[],"aioseo_head":"\n\t\t<!-- All in One SEO Pro 4.9.10 - aioseo.com -->\n\t<meta name=\"description\" content=\"The subatomic structure of a substance determines the presence and strength of magnetic fields.
