(A magnetic dipole may very well be thought of as a small bar magnet. It's the exact same magnetic area therefore a magnet and behaves a similar way in external magnetic fields.) When placed within an external magnetic industry, a magnetic dipole could be subjected to some torque that tends to align it with the field; When the exterior field is not really uniform, the dipole also can be subjected to a pressure.
Some ideas of electromagnetism and solid state physics must be released as being a pre-requisite to be aware of the Doing work of magnetic tapes.
Pfleumer had developed a approach for putting metal stripes on cigarette papers and reasoned that he could in the same way coat a magnetic stripe for use in its place to wire recording.
