A Magnetic Tablet Tale: Apple’s 2018 iPad Pro Contains 102 Magnets
Just when you thought Apple has run out of innovative ideas for their technology, they do it again. In case you missed it, the 2018 version of the iPad Pro features 102 (!!!) small magnets. Although we tend to assume magnets and technology don’t play well together, we have discovered that magnetic mounts are safe to use on our phones and magnetic cases can actually protect your devices during a fall. So it only makes sense that Apple has found a way to incorporate purposeful magnets into their designs.
But why would a tablet need all of these magnets since previous versions functioned without them?
First, the magnets allow you to attach the Apple Pencil, a stylus that, once attached to the tablet, charges wirelessly. You are also able to stick the iPad to the Smart Keyboard Folio featuring a full-sized keyboard and cover. And, if you’re feeling exceptionally brave, you can also stick the iPad to your fridge, whiteboard, or any other magnetic surface.
How Are The Magnets Distributed?
To determine where the magnets are distributed in the tablet, tech vlogger Marques Brown used magnetic field viewing film. To find the magnets, all you have to do is run the film over an object (or in this case, a device), and you are able to see exactly where they ’re placed! Brown discovered that the magnets are mainly distributed along the edges of the tablet.
What is Magnetic Field Viewing Film?
Magnetic field viewing film—also known as field paper—is considered microencapsulated film. Microencapsulation is a process where tiny particles are encased in a coating. Within this green film, there are millions of magnetic particles suspended in oil. When placed over a magnet, the magnet will attract the particles to the areas where the magnet is the strongest—at its poles. On the paper, the poles will appear dark green.
The viewing paper is able to show a variety of permanent magnets, including neodymium, ceramic, samarium-cobalt (SmCo), Alnico (an alloy made up of iron with aluminum, nickel, and cobalt), and flexible magnets. Don’t worry, no magnets are harmed when using the film!
