Magnetism is not measured in watts, it is measured in teslas. The tesla(symbol T) is the SI derived unit of magnetic field strength or magnetic flux density, commonly denoted as B. One tesla is equal to one weber per square meter, and it was defined in 1960 in honour of Nikola Tesla. The strongest fields encountered from permanent magnets are from Halbach spheres, which can be over 4.5 T.
The magnitude of the Earth's magnetic field on the surface ... the field that a compass
aligns itself with ... varies from place to place on Earth, within roughly 0.00003 to
0.00006 tesla . It's presently decreasing in strength, and has decreased by about
10% during the past 150 years.
Another Answer
'Magnetism' is a subject, not a quantity, so it has no units of measurement. You have to specify whichquantities you are referring to, such as flux, flux density, magnetomotive force, reluctance, etc. The main units are as follows:
Flux: weber (pronounced 'vay-ber')
Flux density: tesla (equivalent to a weber per square meter)
Magnetomotive force: ampere (usually spoken as 'ampere turns')
Reluctance: amperes per weber
Magnetic field strength: amperes per metre (note original answer is incorrect for this quantity)

How does wattage affect energy use?
Wattage is a direct measure of how much power is used in an hour. Ex.A 60 Watt light bulb uses 60 watts of power in an hour. Power at your meter is measured in Thousands of Watts or Kilowatts.
What is the difference between amps and volt-amps?
Amps is a measure of current flowing in a circuit. Volt-Amps or (VA) is a measure of power and is equivalent to wattage for a pure resistive load.
How do you find the actual wattage of an electrial component?
Wattage= current*voltage*power factor. Wattage=VI Cos(@)
What is 1000 watt in degree celsius?
Celsius is a measure of temperature, while watts is a measure of power. You cannot convert between them.watts can produce heat that measure temperature, you can compute the increase of termperature per minute, the higher the wattage, the greater increase of temperature per minute will be.
What is the recommended wattage capacity for a power supply for?
If you have a 500 watt power supply and you want to put in a new video card. On the video card's box it will tell you how much power it needs. If it requires less power then you don't need to worry. If it says it requires more, you'll need a bigger power supply with large wattage otherwise you'll kill your computer.
How much power is 1000000 volts?
1,000,000V is not a measure of power. You need the amperage in the equation to figure out the power (wattage). W = A x V
How does wattage affect energy use?
Wattage is a direct measure of how much power is used in an hour. Ex.A 60 Watt light bulb uses 60 watts of power in an hour. Power at your meter is measured in Thousands of Watts or Kilowatts.
Would a multimeter connected in series as part of the circuit measure current or power consumption or voltage or wattage?
Current.
How do I calculate wattage?
Wattage, you mean power. Power = V * I. V - the voltage and I the current.
Power is a measure of?
It is a measure of electrical power. It is Voltage multiplied by Amps. All electrical applicances should give it's wattage or at least it's voltage and Amps so you can work out the wattage. It should be noted that that figure is the maximum that appliance would use.
How can you measure energy output?
Power in watts which can be directly converted to horsepower. RMS wattage is the true measure of the ability to do work. Torque in foot pounds can be a measurement of instantaneous energy.
What is the difference between amps and volt-amps?
Amps is a measure of current flowing in a circuit. Volt-Amps or (VA) is a measure of power and is equivalent to wattage for a pure resistive load.

How do you determine the power wattage capacity needed by a power supply?
Hi there guys, this is the answer you all looking 4.Add up all wattage requirements for all devices that will use the power supply and then add an additional 30%.
Do the same wattage candelabra and incandescent bulbs draw the same power?
Yes, wattage is wattage, is wattage, is wattage. "Power" is calculated in wattage. It equals the voltage times the current in amps. In a light bulb, the resistive filament will cause a certain amount if current to flow making the filament hot and producing light.
Can you measure the physical size of a resistor to determine its wattage?
there might be ways to get the power rating by measuring the size of the resistor. but as the physical size of the resistor increases, its power rating also increases..
How you determine wattage?
wattage is nothing but power product of current and voltage p=v*i
