respond to Good afternoon professor and class, One application of magnetic forces and fields in my daily life is the hard disk drive (HDD) in my computer. A HDD is a device that stores and retrieves data using rapidly rotating disks (or platters) coated with magnetic material. An actuator arm with a read/write head moves across the surface of the platters and uses magnetic fields to read or write bits of information. I think this application is interesting because it shows how magnetic forces and fields can be used to manipulate and store information in a compact and efficient way. HDDs can store large amounts of data, ranging from gigabytes to terabytes, and have a long lifespan. HDDs are also cheaper than other types of storage devices, such as solid-state drives (SSDs), which use flash memory instead of magnetic disks
