The coil.
A radiator
It is related to moving coil type instrument
Different b/w a moving coil instrument and a moving iron instrument
mic or moving iron coil is instrument type works on ac and dc
mic or moving iron coil is instrument type works on ac and dc
in physics
If this is a homework related question, you really should consider trying to solve it yourself before looking at this answer. Otherwise, the value of the lesson, and the reinforcement provided by the assignment, will be lost to you.A moving coil measuring instrument has a coil attached to the indicator, surrounded by a magnet.A moving iron measuring instrument has a magnet attached to the indicator, surrounded by a coil.In both cases, the indicator is driven by magnetic torque caused by current flow in the coil.
I am looking at a 45,000 volt DIS coil package but unlike the aluminum electrodes on the stock coils the performance coils all use brass, brass is about half as electrically conductive as aluminum and no one in tech support can answer why they are advertising brass and being more conductive. The stock coil system is 38,000 volts so my question is whether or not there will be a reduction in the performance coil running at 45,000 volts with half of the electrical conductivity aligned by the electrodes? Do these things really work and are they worth the money?
power must be gotten thru moving parts to the coil slip rings, festoons, tinsel
The function of the moving coil is to deflect the instruments needle across a calibrated scale to give the meter operator an accurate reading of what ever he is testing. The moving coil is given a minute current, through internal instrument circuity, a sample of the potential that is being measured.
An ammeter or other electrical instrument in which a small coil of wire, supported on jeweled bearings between the poles of a permanent magnet, rotates when current is carried to it through spiral springs which also exert a restoring torque on the coil; the position of the coil is indicated by an attached pointer.
