An electromagnetic field has both electric and magnetic components. Units of Weber and Tesla are used to measure magnetic flux and magnetic flux density, while Volts measure electric fields.

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
Why is light in the electromagnetic spectrum Is light a type of electromagnetic radiation But how does that work Light is not magnetic or is it?
Part of the electromagnetic spectrum can be detected by eye, and we call that bit "light". The thing about electromagnetic radiation is that a varying magnetic field causes a (varying) electric field (that's how power stations make electric current) and a varying electric field causes a (varying) magnetic field. So electromagnetic radiation is what you get when a varying electric field creates a varying magnetic field which in turn contributes the varying electric field. The whole thing then appears as bundled varying electric and magnetic field wave system which propagates at the velocity of light, That is why it is called electromagnetic. There are no magnetic poles or electric charges in it, and it can travel through a vacuum.

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 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 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
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.

There could be others, but those are the two I'm aware of.
What determines the direction of polarization of a radiated electromagnetic field?
The polarization of an electromagnetic field is defined as the direction of its E field (electrostatic).
What are facts about electromagnetic fields?
An electromagnetic field is a physical field produced by electrically charged objects. The field can be viewed as the combination of an electric field and a magnetic field. The electromagnetic field may be viewed in two distinct ways: a continuous structure or a discrete structure.
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.
A sentence with the word electromagnetic?
The scientists measured the electromagnetic field.
