Magnetic Separation Basics - Recycling Today

Drum magnets are similar to pulley magnets; however, in the drum magnet, the magnetic element is stationary and positioned only on one side of the drum with a maximum of 180 degrees of arc. While the outer casing of the drum rotates, material is pulled through the magnetic field.

The IBM 650 Magnetic Drum Calculator - Columbia University

The 650 could add or subtract in 1.63 milliseconds, multiply in 12.96 msec, and divide in 16.90 ms. The memory was a rotating magnetic drum with 2000 word (10 digits and sign) capacity and random access time of 2.496 ms. For an additional $1,500/month you could add magnetic core memory of 60 words with access time of .096ms.
