<h2>Summary</h2>
<ul>
<li>Magnetism is a subject that includes the properties of magnets, the effect of the magnetic force on moving charges and currents, and the creation of magnetic fields by currents.</li>
<li>There are two types of magnetic poles, called the north magnetic pole and south magnetic pole.</li>
<li>North magnetic poles are those that are attracted toward the Earth’s geographic north pole.</li>
<li>Like poles repel and unlike poles attract.</li>
<li>Magnetic poles always occur in pairs of north and south—it is not possible to isolate north and south poles.</li>
</ul>
