Drum memory was a magnetic data storage device invented by Gustav Tauschek in 1932 in Austria. [ 1 ] [ 2 ] Drums were widely used in the 1950s and into the 1960s as computer memory . Many early computers, called drum computers or drum machines, used drum memory as the main working memory of the computer. [ 3 ]
Recycling centres use magnetic separation often to separate components from recycling, isolate metals, and purify ores. [1] Overhead magnets, magnetic pulleys, and the magnetic drums were the methods used in the recycling industry. [1] Magnetic separation is also useful in mining iron as it is attracted to a magnet.

1. Tennis Ball. Tennis balls are so useful that you may want to buy some to keep around the house even if you don’t play. For example, half a tennis ball can help screw open tight caps.
Magnetic storage media, primarily hard disks, are widely used to store computer data as well as audio and video signals. In the field of computing, the term magnetic storage is preferred and in the field of audio and video production, the term magnetic recording is more commonly used. The distinction is less technical and more a matter of ...

The magnetic moment and the magnetic field of the electromagnet are proportional to the number of loops of wire, to the cross-section of each loop, and to the current passing through the wire. [45] If the coil of wire is wrapped around a material with no special magnetic properties (e.g., cardboard), it will tend to generate a very weak field.

The IBM 650 Magnetic Drum Data-Processing Machine is an early digital computer produced by IBM in the mid-1950s. [ 2 ] [ 3 ] It was the first mass-produced computer in the world. [ 4 ] [ 5 ] Almost 2,000 systems were produced, the last in 1962, [ 6 ] [ 7 ] and it was the first computer to make a meaningful profit. [ 7 ]
