Musical symbols are marks and symbols in musical notation that indicate various aspects of how a piece of music is to be performed. There are symbols to communicate information about many musical elements, including pitch, duration, dynamics, or articulation of musical notes; tempo, metre, form (e.g., whether sections are repeated), and details about specific playing techniques (e.g., which ...
In a moving magnet cartridge, the stylus cantilever carries a tiny permanent magnet, which is positioned between two sets of fixed coils (in a stereophonic cartridge), forming a tiny electromagnetic generator. As the magnet vibrates in response to the stylus following the record groove, it induces a tiny current in the coils.
An alternator that uses a permanent magnet for its magnetic field is called a magneto. Alternators in power stations driven by steam turbines are called turbo-alternators. Large 50 or 60 Hz three-phase alternators in power plants generate most of the world's electric power, which is distributed by electric power grids. [4]
The magnet creates a magnetic field which is focused by the pickup's pole piece or pieces. [2] The permanent magnet in the pickup magnetizes the guitar string above it. This causes the string to generate a magnetic field which is in alignment with that of the permanent magnet.
Relating to music produced by instruments, as opposed to electric or electronic means ad libitum (commonly ad lib; Latin) At liberty (i.e. the speed and manner of execution are left to the performer. It can also mean improvisation.) adagietto Fairly slowly (but faster than adagio) adagio Slowly adagissimo Very, very slowly affannato, affannoso ...
Dynamos and alternators require a source of power to drive their field coils. This could not be supplied by their own generator's output, without some process of ' bootstrapping '. Henry Wilde , an electrical engineer from Manchester, England, developed a combination of magneto and electro-magnet generator, where the magneto was used only to ...
A North Carolina father is facing criminal charges after authorities allege he left his child isolated in a room with a space heater for more than 12 hours, leading to his death.
magnet wire The class of wire manufactured for winding electromagnetic coils such as in motors or transformers. magnetic blowout A component of a switching device that uses a magnetic field to assist in extinguishing the arc, using a permanent magnet or a coil. magnetic circuit A path through which magnetic flux passes. magnetic constant
