The Hammond clock model "Como" The Hammond Clock Company was founded in 1928 to produce and market clocks that were equipped with Hammond's new motor. The Hammond clock factory manufactured more than 100 different clock models, some simple and cheap, others made from expensive materials such as marble and onyx. [4]
The American Physical Society and the American Association of Physics Teachers recommend a full year of graduate study in electromagnetism for all physics graduate students. [4] A joint task force by those organizations in 2006 found that in 76 of the 80 US physics departments surveyed, a course using John Jackson 's Classical Electrodynamics ...
Laurens Hammond was born in Evanston, Illinois, on January 11, 1895 [1] to William Andrew and Idea Louise Strong Hammond. [2] Laurens showed his great technical prowess from an early age. His father, William, took his own life in January 1897, ostensibly due to failure of the First National Bank of Illinois, which he had founded.
The Hammond organ is an electric organ, invented by Laurens Hammond and John M. Hanert [1] and first manufactured in 1935. [2] Various models were produced, which originally used tonewheels to generate sound via additive synthesis , where component waveform ratios are mixed by sliding switches called drawbars and imitate the pipe organ's registers.
Simplified diagram of how a tonewheel works Goldschmidt tone wheel (1910), used as an early beat frequency oscillator. A tonewheel or tone wheel is a simple electromechanical apparatus used for generating electric musical notes in electromechanical organ instruments such as the Hammond organ and in telephony to generate audible signals such as ringing tone.

In electrical engineering, a transformer is a passive component that transfers electrical energy from one electrical circuit to another circuit, or multiple circuits.A varying current in any coil of the transformer produces a varying magnetic flux in the transformer's core, which induces a varying electromotive force (EMF) across any other coils wound around the same core.
