Any information you want.
Information is stored in the computer's hard drive, which is a magnetic disk read by lasers.
The magnetic strip holds the information of your card.
Digital information is stored in microscopic needles as part of the disk's magnetic coating.
It is stored as magnetic impulses, similar to how a tape recorder records, except that the data is digital rather than analog.
The principle of magnetic recording and reproduction involves encoding information onto a magnetic medium using changing magnetic fields. When recording, information is stored as magnetic patterns on the medium. To reproduce the information, a magnetic head reads the patterns and converts them into electrical signals for playback. The sketches would show the process of writing and reading magnetic data on a medium using a magnetic head.
The behavior of a magnetic field inside a conducting cylinder is such that the field lines run parallel to the axis of the cylinder. This is due to the induced currents in the cylinder that create a magnetic field that opposes the external magnetic field.
A card reader, also known as a magnetic stripe reader, is used to read the information stored on the magnetic strip of a credit card. The reader uses a magnetic head to detect and decode the data on the strip, such as the card number and expiration date.
It sounds like you might be referring to a device called a magnetic card reader, which reads information stored on magnetic stripes found on credit cards, IDs, and other types of cards. These readers use magnetic fields to interpret the data encoded on the magnetic stripe and typically interface with a computer or other device to process the information.
Yes, data is written to and read from a floppy disk using a magnetic read/write head that interacts with the magnetic coating on the disk. When writing data, the magnetic head aligns the magnetic particles on the disk surface to represent the information. When reading data, the head detects the magnetic orientation of the particles to retrieve the stored information.
Yes.
This sounds like a test question. This is not a good way to get an answer.
