Geophone Are Moving Coil Electromagnetic type principle is contained
If you are working with a coil, you should have all parts of the coil and knowledge to work with them. In the related links box below, I posted a websited which has all this knowledge and another one about builduing the tesla coil.
i have no clue
Moving coil galvanometer is used to detect unknown resitance of the both ac or dc circuits :)deepak instrumentation engineerAnswerA 'galvanometer' is simply an instrument that detects and measures small currents; 'moving coil' describes its operating principle. A moving-coil galvanometer is a d.c. instrument; if subject to a.c., then it will simply vibrate as it will not be able to respond the the frequency (unless the frequency is very low, in which case, it will sweep back and forth in step with that frequency).The moving-coil principle is applied to other instruments, and can be used in the construction of multimeters. In the case of a multimeter, a rectifier circuit is incorporated so that it can be used to measure a.c. currents and voltages.
A moving coil galvanometer is a type of scanning device used in the transportation and trucking industry. The vehicle is pulled through a fixed scanner while an operator watches a closed circuit television.

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.
An ammeter consists of a coil with very low resistance. when electric current flows through the coil, the coil induces a magnetic field which turns the needle.
it will smash to each other & make flex
Using a megger you check from either positive or nuetral to ground. The megger should read open (usually OL). It doesnt matter which connection you choose as long as one is ground. If the megger shows anything other than open the windings are bad.
The working principle of these instruments is same as that of the d'Arsonval type of galvanometers, the difference being that a direct reading instrument is provided with a pointer and a scale. The basic principle of this device is the interaction of magnetic field of the compass (a permanent magnet) and the field around the conductor (a simple electromagnet)
By Megger testing (meggering) of the motor any one can measure the IR of the motor. MEGGER is a device used to measure IR. Analog Megger device may generate 500 volts..it gives coil to coil or coil to body IR value...it should not be less than 2 Mega ohm, generally it should be or kept more than 5 mega ohm...thanks ...DEEPAK RAJPUT
galvanometer is an elctromechanical instrment which is used to indicate the current or voltage. principle of working-it works on the principle of conservation of electrical energy to mechanical energy.
A Tesla coil operates on the principles of electromagnetic induction and resonance. It consists of two main circuits, a primary and a secondary coil. When high voltage is applied to the primary coil, it creates a rapidly alternating magnetic field, which induces a high voltage in the secondary coil through electromagnetic induction. Resonance between the two coils allows for the efficient transfer of energy and the generation of high-voltage, high-frequency electrical currents.
To make a working model for mutual induction, you can use two coils of wire wound around a common core. Connect one coil to a power source, then observe how an induced current is generated in the other coil due to mutual induction when the current in the first coil changes. You can measure this induced current with a multimeter to demonstrate the principle of mutual induction.
The ballistic galvanometer principle states that when a current-carrying coil is suddenly disconnected from a source, the coil carries on moving because of its momentum. The deflection of the coil is proportional to the charge that passed through the coil while it was connected.
The principle of a dynamo is based on Faraday's law of electromagnetic induction, which states that a change in magnetic field within a coil of wire will induce an electromotive force (EMF) in the coil. This EMF can then drive a current in the circuit connected to the coil, generating electrical power.
