Hall Probe. When the Hall Probe is held so that the magnetic field lines are passing at right angles through the sensor of the probe, the meter gives a reading of the value of magnetic flux density (B).

What is the unit of energy of inductor?
I am not entirely sure what you mean. Energy is measured in joules. The energy stored in an inductor would therefore also be measured in joules. The "strength" of an inductor is measured in henry, but that is not an energy unit.
What are the standard units of electrical energy?
In the SI, any type of energy is measured in joules.
What is the difference between mva and mw?
For clarification, the correct symbols are 'MV.A' and 'MW' -where a capital 'M' represents 'mega'. A lower case 'm' stands for 'milli' -quite a difference. And the symbols for ampere and volt are an upper case A and an uppercase V.When an electric current flows through a load, the temperature of the load increases above ambient temperature, and energy is therefore lost to the surroundings through heat transfer. This represents a permanent loss of energy from the circuit. The rate at which this energy is lost is called the true power of the circuit, measured in watts.At the same time, whenever current flows, a magnetic field is set up around the conductor. As the current increases in value during the first quarter-cycle, this field expands and energy is stored within that field. During the next quarter-cycle, as the current reduces in value, the energy stored in the magnetic field is returned to the circuit. So, while there is movement of energy, there is no net loss of energy from the circuit. The rate at which this energy transfer is taking place is called the reactive power of the circuit, measured in reactive volt amperes. (A similar thing happens in capacitive circuits, although the energy is stored/returned in an electric, rather than in a magnetic, field).The vector sum of true power and reactive power is called the apparent power of the circuit, measured in volt amperes. That is:(Apparent Power)2 = (True Power)2+ (Reactive Power)2(Technically, there is absolutely no reason why true power, reactive power, and apparent power can't all be measured in watts -it is only traditional to use different units!)It is very easy to measure the apparent power of a circuit, because it is the product of the voltage applied to the load and the current flowing through it -and we could use a voltmeter and an ammeter to determine these values. It is rather more difficult to measure the true power because the voltage and the current must be multiplied by the load's power factor, which is not necessarily known. Nevertheless, it can be measured directly, using a wattmeter.
What is trapped energy of inductor?
An inductor resists a change in current. It does this by converting the current into a magnetic field. If the current then changes, the collapsing or increasing magnetic field will buck the attempted change through electromagnetic energy conversion.
Electrical energy can be measured in units called what not watt?
All forms of energy are measured using the same units. The SI unit for energy is the joule (J). However, the unit used by electrical utility companies is the kilowatt hour (kW.h).
What produces the electrical energy that is being measured by the voltmeter?
Any electrical device that you connect it to.
What do volts do?
the amount of energy of electrons is measured in volts by using a voltmeter
What kind of movement creates electrical energy?
Movement of a wire in a magnetic field. If a loop of wire is moved in a magnetic field, it produces a voltage across its ends that can be measured on a voltmeter, resulting from the change in the magnetic flux linking the coil. If a resistor is connected across the ends, a current will flow and a force is needed to move the wire in the magnetic field. The energy supplied by the movement of the coil appears as electrical energy in the resistor, heating it up. That is the principle of an electric generator.
Electric energy used in homes is measured using a. a voltmeter. c. an ammeter. b. an ohmmeter. d. a kilowatthour meter.?
D. A kilowatthour meter
How are the energy and wavelength of electro magnetic radiation related?
The Relationship is the 'Flux' of the magnetic field.Changing the amount of energy will not effect the wavelength (except to choke off the field when it becomes too dense)and increasing the wavelength will increase the energy density (flux)
In what unit do you measure magnetic energy in?
asked this question on yahoo answers and this came up Answer 1 Magnetism generates a force and by itself it is not an energy. You generate energy by letting the magnetic force pull things together. In the same way that a hill is not an energy but if you roll down it you generate energy. To get back to the top you have to put the energy back in. Answer 2 Gauss is the unit of magnetic induction or magnetic flux density. I think this might be the answer to your question, but I am not sure
What is meaning of flux density?
Like the number of sunspots, the Flux Density Values reflect the Sun's magnetic activity, which affects the rate at which the Sun radiates energy and warmth.

Is there magnetic energy in the universe?

What is the purpose of B-H curve?
The purpose of the B-H curve is to quantify the relationship between the magnetic flux density (B) and the magnetic field strength (H) in a material. It helps in understanding the magnetic properties of materials, such as their magnetization behavior and saturation levels, which is essential for designing magnetic devices and systems.
