How Do Our Phones Know Where North Is? Unveiling the Magnetism in Your Smartphone

Explain Station

In today's episode, we take a deep dive into something we use every day but rarely think about: how our phones know where north is without a compass needle inside. Join us as we explore:The Hall Effect: Understanding the physics principle that allows phones to sense magnetism.Micro Magnetometers: How tiny sensors smaller than a grain of rice detect the Earth's magnetic field.Three-Dimensional Sensing: The ability of our phones to determine direction no matter how we hold them.Applications in ...
