3D virtual reality is nothing new. However, it is almost a high-tech product and expensive before.
In 2014, the most popular VR Google Cardboard came out. It is a simple structure of folding paperboard, two filters, and neodymium ring magnet. The ring NdFeB magnet is used as the magnetic switch.
Since then, more and more people began playing Google cardboard app. And lots of 3D virtual reality kits have also appeared.
For example, if you need a magnet to trigger the click-in-app, there is a magnet switch on eBay online store for Google Cardboard Inspired Virtual Reality Kit.
The whole magnet assembly is well designed with ABS part and neodymium magnets which can work with Google Cardboard app perfectly.
As we all know, the neodymium magnet is the strongest permanent magnet commercially available in the world. That means it is small in volume and big in use.
The permanent strong magnets used here include neodymium countersunk magnet or ring neodymium magnet with nickel-copper-nickel triple layer coated and uncoated dark color ferrite in the shape of a disc.
Obviously, this ferrite magnet can be replaced by neodymium disc magnet; the reason to use ferrite is the low cost.
