Tape recording is one of the practical applications on magnetism and electromagnetism. The first tape recording was performed by Danish inventor Valdemar Poulsen and used a steel wire enclosure to place the tape in the modern record. The tapes have been used for recording in the 1920s.
The tape is composed of a plastic chip coated with special magnetic iron oxide powder. The recorder uses a magnet to record the sounds on the tape by switching the sounds first to the electrical signals through the microphone. The rippling airwaves that make up the sound turn into a variable electric current that is transmitted by wires to the recorded head. The electrical signals are recorded on the tape passing through it with a fixed speed.The recorded head consists of a narrow-banded iron hoop wrapped around multiple wire rolls to make it an electromagnetism and the flow of electrical current in these files. A magnetic field is generated across the gap between the poles of the magnet and the band passes very close to the gap. Iron oxide is magnetized by magnetic field Of the registered head. When the current of the forces of strong magnetic field and intensifies the magnetization of the tape.
Thus, the current changes are recorded on the tape.
When the tape turns back to hear the tape passes on a similar head called the head of the restoration as quickly as ordered upon registration. In the course of the passage of the tape, its magnetic parts generate a magnetic field and a varying thickness in the head of the recovery head. This field generates a heterogeneous electric current that is exactly the same as the current generated by the microphone during the recording process.The recorded sound is restored at the current of the current in the device's speaker.It features a tape recorder that can strip and erase it and use it again to record other things on it.The survey is performed by a third head similar to the other two heads, the head of the survey. This generates a fast-rotating magnetic field that increases and decreases several times per second, removing the magnetic tape.The tape recorder is used to record and retrieve the sound on demand and the TV recorder works similarly to record the sounds and television images on the videotape as magnetic signals that can be restored and broadcast again when needed.
