Question

identify the relevant magnetic properties used for memory storage​

Answer 1

Answer:

Solution: By eliminating the row and column of an element, the determinant of remaining elements is the minor of the element, i.e. M i × j {{M}_{i\times j}} Mi×j and by using formula ( − 1 ) i + j M i × j {{\left( -1 \right)}^{i+j}}{{M}_{i\times j}} (−1)i+jMi×j we will get the cofactor of the element.

Answer 2

Magnetic storage uses different patterns of magnetisation in a magnetizable material to store data and is a form of non-volatile memory. The information is accessed using one or more read/write heads. ... Other examples of magnetic storage media include floppy disks, magnetic tape, and magnetic stripes on credit cards.
