Why pmmc instrument is cannot be used to measure ac?
Pmmc meter are most accurate instrument for DC measurement however they are unable to measure the AC quantity. The working principle is as follows: a moving coil is free to move in a external static magnetic field. And the pointer moves according to the interaction of two fields, field of static mag. and that of measuring quantity. Now in case of it is impossible to produce a sustained magnetic field, that's why we can not use PMMC to measure the ac.
What instrument could you use to measure a football field?
The type of measurement that is used to measure a soccer field is based on Law 1 of the Laws of the Games. These are codified rules that define the game of soccer.
Would you use volume weight length density or mass to measure how long a football field is?
Length would be the most appropriate unit of measurement
Does an electromagnetic wave have an electric field?
Yes
Can you use millimeters to measure a baseball field?
Yes, you can use millimeters to measure a baseball field, but it would not be a practical unit of measurement due to the large size of the field. A more common unit like meters or feet would be more suitable for measuring the dimensions of a baseball field.
What methods are commonly used for electrical field measurement in the industry?
Common methods for electrical field measurement in the industry include using electromagnetic field meters, electric field probes, and oscilloscopes. These tools are used to measure the strength and direction of electric fields in various applications such as power distribution, telecommunications, and electronic device testing.
What instrument is used to measure the magnetic field strength at the center of a magnetizing coil?
A teslameter is the instrument commonly used to measure the magnetic field strength at the center of a magnetizing coil. It is designed to detect and measure the magnetic field in tesla units.
What instrument measures charge?
It depends on what kind of reading you want. An electrician will usually carry around a multimeter which can measure voltage, current, and resistance. Another piece of equipment that can "determine the presence of electric charge" would be a Electromagnetic Field (EMF) detector, since all electrical appliances/wires produce an electromagnetic field. There could be others, but those are the two I'm aware of.

What methods are commonly used for electric field measurement?
Common methods for electric field measurement include using a voltmeter to measure voltage, using a field mill to measure electric field strength, and using a Faraday cage to shield from external electric fields.
What device is used for electromagnetic radiation?
Electromagnetic radiation is just light. You can measure light with a light meter, which tells you intensity, or a camera sensitive to different frequencies. You can also use a magnetometer (Gaussmeter) to measure the B field component or a voltmeter to measure the E field component.
What unit of measurement would you use to measure the length of a football field?
The meter.
What unit of measurement would you use to measure a soccer field?
In the US, I would use yards.
What would some of the problems be using the cubit?
the measurement is not always exact and say you were to measure a football field and your measurement were to be exact it would be close to impossible
How can one accurately measure electromagnetic fields?
One can accurately measure electromagnetic fields using specialized instruments called electromagnetic field meters. These meters detect and quantify the strength of electromagnetic fields in a given area, providing valuable data for assessing potential health risks and ensuring compliance with safety standards.
What instrument measures electromagnetic force?
It depends on what kind of reading you want. An electrician will usually carry around a multimeter which can measure voltage, current, and resistance. Another piece of equipment that can "determine the presence of electric charge" would be a Electromagnetic Field (EMF) detector, since all electrical appliances/wires produce an electromagnetic field. There could be others, but those are the two I'm aware of.
When electric and magnetic fields both exist it is called an?
Not really. You could have both an electric field and a magnetic field occupying the same space at the same time but they wouldn't 'make the definition' of electromagnetic until they began to fluxuate in phase at a harmonized frequency.
