Is the strength of an electromagnet measured in volts?
That's a tricky question. Well, technically it is not measured in volts. The strength of an electromagnet depends on the electrical current which flows through its wires, but not on what drives that current. The current is measured in the amount of charge per unit time that flows through the wires. But when it comes to measuring the magnet, you have to refer to the magnetic field. Without it, there wouldn't be any "magnet." So, logically, to measure the strength of the magnet you must first measure the strength of the magnetic field. It's strength is measured in Volts per meter(V/m). So to measure the strength of the electromagnet you must measure the strength of the magnetic field whose formula is found in the next to last sentence. Hope this helps.
What is the unit for magnetic force?
The SI unit for force is the newton, N = kg m s-2. Magnetic field strength is measured in tesla, T = V s m-2 (or N A-1 m-1, or kg A-1 s-2, etc.). The strength of Earth's magnetic field is about 3 x 10-5 T.
What does the magnetic flux per unit area indicate?
the strength of a magnetic field
What is the sl unit for magnetic field?
Different units are used. From Wikipedia: "The term [magnetic field] is used for two distinct but closely related fields denoted by the symbols B and H, where H is measured in units of amperes per meter ... B is measured in teslas (symbol:T) and newtons per meter per ampere(symbol: N·m−1·A−1 or N/(m·A)) in the SI. ..."

How will calculate the power of magnet?
The electric power is measured the same as in any other electric circuit, in watts. You calculate this by multiplying the current (in amps) by the potential difference (in volts) across the circuit. So: P = I V If you meant how do we measure the strength of the magnetic field generated, there are two different vector fields that may be called "magnetic field". These are the H-field and the B-field. The H-field may also be called the "magnetic field intensity", the "magnetic field strength", the "auxiliary magnetic field" or the "magnetising field". It is measured in amps per metre. The B-field may also be called the "magnetic flux density", the "magnetic induction", or the "magnetic field". It is measured in teslas.

Is magnetic field strength a vector quantity?
When one refers to the strength of a magnetic field, they're usually referring to the scalar magnitude of the magnetic field vector, so no.
How strong is earth's magnetic field?
Not very strong in comparison with a typical small "bar magnet" which has a field strength of roughly 100 gauss. Earth's magnetic field strength at the surface is about 0.3 to 0.6 gauss. That's stronger than some planets and weaker than others.
How do you calculate the magnetic field strength in an injector cyclotron?
- Magnetic field strength is the intensity of a magnetic field at a given location. Historically, a distinction is made between magnetic field strength H, measured in ampere/meter, and magnetic flux density B, measured in tesla. Magnetic field strength is defined as the mechanical force (newton) on a wire of unit length (m) with unit electric current(A). The unit of the magnetic field, therefore, is newton/ (ampere x meter), which is called tesla. The magnetic field may be visualized by magnetic field lines. The field strength then corresponds to the density of the field lines. The total number of magnetic field lines penetrating an area is called magnetic flux. The unit of the magnetic flux is tesla x m2 = weber. The older units for the magnetic flux, maxwell = 10-8 weber, and for the magnetic flux density, gauss = maxwell / cm2 = 10-4 tesla, are not to be used any more. Magnetic flux density diminishes with increasing distance from a straight current-carrying wire or a straight line connecting a pair of magnetic poles around which the magnetic field is stable. At a given location in the vicinity of a current-carrying wire, the magnetic flux density is directly proportional to the current in amperes. If a ferromagnetic object such as a piece of iron is brought into a magnetic field, the "magnetic force" exerted on that object is directly proportional to the gradient of the magnetic field strength where the object is located. ------------------------------------------------------------------- B=μH Magnetic field in Solenoid B=μnI where n is turns/m So H=nI --------------------------------------------
What is the difference between magnatic field strength and pole strength?
Pole strength is ability of poles to produce lines of force where is field strength is force which a magnetic poles experiences when places in magnetic field.
What do strength mean?
here strength means magnetic field strength
How are magnetic fields measured?
We can say magnetic field strength is a measure of magnetic strength of a magnet.. like electric field density in electrostatics.... ex consider a current carrying wire which produce a magnetic field in radial direction... by using ampere law.. we can easily find magnetic field strength at a point (r distance from wire)... H=I/(2*3.14*r).. its like finding a electric field intensity by Guass law.......The magnetic field ranges from less than 30 micro-teslas (0.3 gauss) to 60 microteslas (0.6 gauss) The strength varies daily usually about 25 nanoteslas (nT) with variations every second of 1 nTAnswerMagnetic field strength (symbol H) is defined as the magnetomotive force per unit length of a magnetic circuit, and is expressed in amperes per metre (A/m). The original answer appears to be defining flux density(expressed in teslas), not magnetic field strength.
