The basics of magnets are pretty simple. You've got a north and south pole and as we learned in grade school, opposites attract and similar poles repel. A company by the name of Correlated Magnetics has done some serious thinking outside of the box to create what they call "programmable" magnets - otherwise known as polymagnets.
Destin Sandlin, host of the YouTube channel Smarter Every Day, recently visited the company to investigate how they're able to print magnetic designs on the surface of magnets. What they're essentially doing is creating a custom magnetic field on the face of any magnet that both attracts and repels.
As you'll see, the technology is so new that its creators haven't even had enough time to think through all of the potential applications.
