Anyone have a source of information about the effective range of a magnetic field that would cause damage to computerized or other electronic equipment? I'm researching an option to use rare earth magnets to assemble something, but I want to make sure that it won't screw up the electronic equipment that will be close to the magnets (but not in direct contact).
The use of magnetic tape improved the performance of computers by giving them the ability to read and write data quickly and reliably.
No.

yes
Punched cards & magnetic tape
Many different types of memory were used in first generation computers, a few of the most commonly used were:electrostatic cathode ray tubes (DRAM)sonic delay lines (DSAM)electrostatic selectron tubes (SRAM)magnetic drums (NVSSAM)magnetic disks (NVSSAM)magnetic core stacks (NVSRAM)Magnetic core memory eventually became dominate.Second and third generation computers continued to use sonic delay line memory, magnetic disk memory, and magnetic core memory (with magnetic core memory still dominating).Late in the third generation computers solid state memory chips replaced all other types of memory.Fourth generation computers used only solid state memory chips.
Magnetic drums
Magnetic discs are a storage medium that uses magnetic materials to store data. Common examples include hard disk drives (HDDs) and floppy disks. Magnetic discs are commonly used in computers and other electronic devices for data storage and retrieval.
No, magnetic paint just allows magnets to stick to the paint, it is not magnetic itself. Even if it was, it would be much too weak to cause any damage.
Magnetic forces are not necessarily bad for computers, as mechanical hard disks use them to store information. However, you shouldn't place any magnetic objects near them as it will ruin your data that's store on those kinds of disks.
Tubes, magnetic logic, and transistors.
It is used for storing information which can be retrieved on a tape player or some computers.
