Editing Tape recorder (section)

=== Electrical ===
Due to [[electromagnetism]], [[electric current]] flowing in the coils of the tape head creates a fluctuating magnetic field. This causes the magnetic material on the tape, which is moving past and in contact with the head, to align in a manner proportional to the original signal. The signal can be reproduced by running the tape back across the tape head, where the reverse process occurs – the magnetic imprint on the tape [[Faraday's law of induction|induces]] a small current in the read head which approximates the original signal and is then amplified for playback. Many tape recorders are capable of recording and playing back simultaneously by means of separate record and playback heads.<ref>{{cite book | last=Hurtig | first=B. | title=Multi-Track Recording for Musicians | publisher=Alfred Music Publishing | isbn=978-1-4574-2484-7 | url=https://books.google.com/books?id=ByJG1iwUHBAC&pg=PA7 | access-date=2024-08-09 | page=7}}</ref>
