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.
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.
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.
Length would be the most appropriate unit of measurement
Yes
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.
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.
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.

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.
The meter.
In the US, I would use yards.
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

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.
The polarization of an electromagnetic field is defined as the direction of its E field (electrostatic).

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.
