What feature of earth makes a compass needle point north?
What features of the earth makes a compass needle point north
A compass needle points northward due to earths?
magnetic field, which aligns the needle with the north direction. This field is created by the movement of the Earth's outer core, composed of molten iron and nickel, which generates a magnetic field as the Earth rotates.
What causes a compass needle to point to geographic north?
A compass needle is a magnet that aligns itself with the Earth's magnetic field, which is generated by the movement of molten iron in the planet's outer core. The needle is attracted to the magnetic north pole, which is close to but not exactly the same as the geographic North Pole.
An unmagnetized needle will not attract another unmagnetized needle but if one end of the needle is in contact with a magnet the other end will attract the other needle explain?
When one end of the unmagnetized needle is in contact with a magnet, the magnetic field from the magnet induces magnetism in the needle. This results in the end of the needle touching the magnet becoming a magnetic pole, and the other end becoming an opposite pole. The opposite poles attract each other, causing the unmagnetized needle to attract another needle when in contact with a magnet.
What is a device that has a magnetized needle that can spin freely?
A compass has a magnetized needle that can spin freely.
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
When testing a capacitor with an analog ohmmeter the needle on the meter should?
. . be visible.
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 Conclusion of analog and digital multimeter?
The only different is one has a needle, the other digital numbers-same as with analog and digital watches.
Why is a pulsing voltage easiest to read on an analog meter?
This is because digital meters do not continuously update the display. My meter for instance only shows a new number twice a second. If the voltage peaks between updates, you will never see it. Analog meters continuously follow the voltage, and the eye can follow the pointer as it peaks. Many electricians and technicans still hang on to their beloved Simpson 260 analog meter for this very reason. Many digital meters now have a little bargraph below the main display, set to act like an analog meter, to make this type of visual measurement possible. It should be noted that even the analog meter does not respond perfectly to voltages that change quickly, because the physical mass of the meter movement cannot accelerate insantaneously. So, if you see the needle "pulse", you know there was one, but you cannot rely on the needle to show the true peak. Such measurements are used to see the trend or get a rough idea of what is happening in the circuit. If you need to find the exact value, use an oscilloscope!
How tall is the space needle in meters?
The Space Needle in Seattle is 184 meters tall.
When a needle of an analog ohmmeter indicates infinity the resistor being measured is?
Open
What would cause the speedometer needle not to work when the headlights are on?
If it's an electronic (analog) speedometer needle, you probably have a problem with the dasboard grounding.
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.
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.
What is analog tester?
simply means the tester's measurement is displayed in an analog way (not digital) For example: a moving needle that points to a scale a clock with hands is ANALOG a clock that displays the time like this (11:55pm) is DIGITAL
How do you know that analog multimeter is working or not?
To check if an analog multimeter is functioning properly, first ensure it's set to the correct measurement range. You can test it by measuring a known voltage or resistance; for instance, using a fresh battery or a known resistor value. Observe the needle movement—if it responds accurately and consistently to the test input, the multimeter is likely working. Additionally, you can verify continuity by checking if the needle moves when the probes are shorted together.
