Head – The device that reads and writes the information—magnetic or optical—on the disk surface.
That is called a magnetic compass.
A magnetometer.
A hard disk drive is a type of magnetic storage device. A magnetic storage device stores data on a magnetized medium. Other types of magnetic storage includes magnetic recording tapes and the stripes on credit cards.
It's called formatting.

A storage device.
One can accurately measure the strength of a magnetic field using a device called a magnetometer. This device detects and quantifies the magnetic field strength by measuring the force exerted on a magnetic material within the field. The measurement is typically expressed in units of tesla or gauss.
One can see magnetic fields by using a device called a magnetic field viewer, which contains tiny particles that align with the magnetic field lines, making them visible to the human eye.
A compass is a device that indicates the direction of the magnetic flux. It aligns with the Earth's magnetic field and points towards the magnetic North Pole.
