reliable storage of data, the recording material needs to resist self-demagnetisation, which occurs when the magnetic domains repel each other. Magnetic...

magnetisation and demagnetisation (where not demagnetised thermally) occur through intermediate states as shown (right). The magnetising and demagnetising wavelengths...

magnetization in knowing the magnetic properties of certain rock minerals. Demagnetisation to remove isothermal remanent magnetisation thus became a common practice...

Anatoly Alexandrov. By November 1941, they had devised a method of demagnetising ships to protect them from German mines, which was in active use until...

several reasons for this: first, if the superconductors should become demagnetised through (i) flux creep, (ii) repeatedly applied perpendicular fields...

They turned the ships to the FNFL on 20 September. Both ships were demagnetised as a precaution against mines, and armed with two 8 mm (0.315 in) Hotchkiss...
