Magnetism is a fascinating phenomenon. Simply put, magnetism is a strong force of attraction created by electric currents . Today, we know all about magnets and magnetic fields. To ancient people, however, it must have seemed like magic!

We all remember playing with magnets in science classes, and, you have to admit, it was a curious and fun activity. Yet, they contribute much more than entertainment. Magnetism and electromagnetism have countless applications, from electric appliances and tech gadgets to nuclear fusion. We know what you're thinking: that's a broad spectrum.

The way we use magnets very much depends on their strength. In this video, we've gathered together all the most powerful and interesting magnets in the world.


But before we dive in, hear this: the strength of a magnet is calculated by many different factors . The one we review here is the intensity of the magnetic field created, measured in Teslas or Gauss.
