What is Conducting: Definition and 560 Discussions
Conducting is the art of directing a musical performance, such as an orchestral or choral concert. It has been defined as "the art of directing the simultaneous performance of several players or singers by the use of gesture." The primary duties of the conductor are to interpret the score in a way which reflects the specific indications in that score, set the tempo, ensure correct entries by ensemble members, and "shape" the phrasing where appropriate. Conductors communicate with their musicians primarily through hand gestures, usually with the aid of a baton, and may use other gestures or signals such as eye contact. A conductor usually supplements their direction with verbal instructions to their musicians in rehearsal.The conductor typically stands on a raised podium with a large music stand for the full score, which contains the musical notation for all the instruments or voices. Since the mid-19th century, most conductors have not played an instrument when conducting, although in earlier periods of classical music history, leading an ensemble while playing an instrument was common. In Baroque music from the 1600s to the 1750s, the group would typically be led by the harpsichordist or first violinist (see concertmaster), an approach that in modern times has been revived by several music directors for music from this period. Conducting while playing a piano or synthesizer may also be done with musical theatre pit orchestras. Communication is typically mostly non-verbal during a performance. However, in rehearsals, frequent interruptions allow the conductor to give verbal directions as to how the music should be played or sung.
Conductors act as guides to the orchestras or choirs they conduct. They choose the works to be performed and study their scores, to which they may make certain adjustments (such as in tempo, articulation, phrasing, repetitions of sections), work out their interpretation, and relay their vision to the performers. They may also attend to organizational matters, such as scheduling rehearsals, planning a concert season, hearing auditions and selecting members, and promoting their ensemble in the media. Orchestras, choirs, concert bands, and other sizable musical ensembles such as big bands are usually led by conductors.
Two 0.68 m long conducting rods are rotating at the same speed in opposite directions, and both are perpendicular to a 4.7 T magnetic field. As the drawing shows, the ends of these rods come to within 1.0mm of each other as they rotate. More-over, the fixed ends about which the rods are rotating...
A conducting sphere that carries a total charge of 6 micro C is placed at the center of a conducting spherical shell that also carries a total charge of 6 micro C .
(a) Determine the charge on the inner surface of the shell.
(b) Determine the total charge on the outer surface of the shell...
"a conducting slab has infinite extent in the x and y directions and thickness L in the z direction. The slab is centered at z=0 and carries a uniform current density J=Ji where i, j, and k are unit vectors in the x, y, and z directiosn."

Howdie all,
I'm soo glad I found this forum, people are genuinely working together instead of ignoring their fellow physics brethren =)
A pair of square parallel conducting plates, having sides of length .05 meter, are .01 meter apart and are connected to a 200 volt power supply. An electron...
In one of our exercises, there is a conducting sphere (S2) with a cavity inside (S1). A point charge is placed inside the cavity. We were told to try and find the electric field outside by following a set of steps.
1. Imagine that S2 is grounded. In that case, the charge on the cavity wall...
A square conducting loop with sides a lies on a table a distance s from a very long straight wire carryinga current I.
a) Derive an expression for the magnetic flux through the loop.
b) Derive an expression for the EMF induced in the loop if it is pulled away in a direction orthogonal to...
consider two conducting loops with fixed geometries and at fixed positions. Let I1 and I2 be the currents flowing in the loops 1 and 2.
how does Faraday's Law allow the currents I1 and I2 to affect each other?
farday's law says that changing the flux between loops 1 will induce an emf in...
Does anybody know off of the top of their head:
1)The most conducting metal
2)A conducting metal with the roughest surface (looking for surface area)

Yo, d00dz, I can't remember how to find the electric field inside a conducting wire (actually a coaxial cable)
Here's the exact text of the problem:
A coaxial cable (inner radius a, outer radius b) is used as a transmission line between a battery E and a resistor R, as shown in Fig 19...
