Different b/w a moving coil instrument and a moving iron instrument
Megger is related to a hot wire instrument with a moving coil. The megger uses a moving coil to measure insulation resistance in electrical circuits and equipment. This type of instrument is specifically designed for insulation testing.
To replace a heating coil in a heating system, first turn off the power to the system. Next, locate the coil and remove any covers or panels blocking access. Disconnect the wires and tubing connected to the coil. Remove the old coil and replace it with a new one of the same size and type. Reconnect the wires and tubing, then turn the power back on to test the new 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?
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.
power must be gotten thru moving parts to the coil slip rings, festoons, tinsel
Level Wound Coils are used in various applications, including refrigeration and air conditioning systems.
