A: Directly from whatever you are measuring as a Small current to move the coil to indicate current flow. That current can be calibrated to read voltage or current on the meter itself

How an analog volt meter works?
The meter movement has a current flowing through a coil. That coil is on a magnet. The electromagnet with the needle moves according to the current flow. That flow is established by resistive ladders inside the meter.
When testing a capacitor with an analog ohmmeter the needle on the meter should?
. . be visible.
What is a meter stop?
A meter stop is a small metal or plastic peg placed just beyond the limits of normal meter movement on an analog meter movement to prevent the needle from moving too far off scale. Overloading a meter so that it hits the meter stop hard is often called "pegging" the meter and can damage it by bending the needle.
What Do Amps Measure?
You can measure the electrical current with an amp meter. Amperage measures the current flow.

What is a clamp meter?
It is a multimeter with a clamp on facility to measure current using it as a current transformer.

How can measure nutral and earthing wire?
Nutral wire can be measured by using clamp meter, if there is a current passing through the wire, we got a reading in the clamp meter i.e. 2A. If we clamp the earth wire by the clamp meter the reading will be zero.

Why are analog meters used in vehicles?
If you are cruising down the freeway, you can get about the same information on, say, your speed, if you look at an analog meter as a digital one. But if you are braking and your speed is changing, a digital meter will be "fluttering" as it continuously gets a new reading to post, and it won't be able to tell you how fast you're going. (This had to do with the way the sensors "sample" the speed to display it.) In the analog meter, the needle will be falling as you slow down, and the human brain has a better "grasp" of the "meaning" of the falling needle than it has of blinking numbers on a display. Certainly as the needle on an analog meter passes a specific mile-per-hour marker, you can see how fast you were going. But it is the value of the moving needle in the analog meter and the ability of the brain to "understand" it that makes it so much more effective than a digital display.
What are the differences of a analog multi-tester to a digital multi-tester?
analog is a D'arsonal movement (an indicator needle over a scaled background) and a digital meter is a LCD display that has no movement
What is a meter stop?
A meter stop is a small metal or plastic peg placed just beyond the limits of normal meter movement on an analog meter movement to prevent the needle from moving too far off scale. Overloading a meter so that it hits the meter stop hard is often called "pegging" the meter and can damage it by bending the needle.
What Do Amps Measure?
You can measure the electrical current with an amp meter. Amperage measures the current flow.
Why ohm meter scale is reverse of other measuring devices?
For an analog ohmmeter, with a needle that moves left and right: The needle is spring loaded; when current is running through the meter, the current causes a small magnetic field in the windings of the meter mechanism, causing it do deflect to the right. If you're measuring current or voltage, if no current is running through the meter, then no deflection, so it should read zero on the left hand side of the scale. When measuring ohms (resistance) on an unenergized circuit, the battery in the meter provides the current. When you short the 2 leads together you have zero resistance to current (0 ohms). When you have an open circuit, no current flows, so there is an infinite resistance. So infinity is on the left side of the scale when no deflection, and zero is on the right side with maximum deflection (maximum current).
How does a digital multimeter eliminate parallax error?
When reading the needle on an analog meter, you can get a slightly different reading depending on the position of your eye relative to the needle and the scale behind the needle. This is parallax. The digital meter reads the exact value measured (to the accuracy of the meter), and then displays it in the form of "numbers" or "digits" so your eye is not interpreting the value from a scale.
