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 unit of measurement is used to measure an electromagnetic field and what instrument is used to measure that?
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.
SI unit of magnetic-induction?
Electromagnetic induction is the process of inducing electric current in a coil with the help of a magnet.Whenever a conductor is moved through a magnetic field, or the magnetic field fluctuates in strength (as with an AC electromagnet), a current will be induced in that conductor. Induction cooktops work by passing a large AC current through a conductor under the cooktop, creating a fluctuating magnetic field which induces an electric current through the cookware - heating the cookware by electrical resistance.The process by which a substance, such as iron or steel, becomes magnetized by a magnetic field. The induced magnetism is produced by the force of the field radiating from the poles of a magnet.CommentFurther to the original answer, it is a voltage that is induced into a conductor, NOT a current.

What is the difference between magneticomotive force and magnetic field intensity?
Magnetic field intensity speaks of the strength of a magnetic field, usually in Tesla, whereas forces deal with units of Newtons and are fundamentally characterized through F=MA in conjunction with Newton's Laws.

What is 2825 gauss?
Gauss is an old (cgs) unit for magnetic field strength. To convert to modern units (tesla), divide by 10,000.
What is the magnetic field expressed in gauss of a refrigerator magnet with a magnetic field of 0.3T?
Thw magnetic fringe field should not exceed how much gauss units?
What is the interactions between the what?
The main one is that electric current, which consists of electric charges flowing along a wire, sets up a magnetic field around the wire. The field lines are circles, with the magnetic field at right-angles to the current. The magnetic field intensity at distance r from the wire is given in SI units by: H = i/(2.pi.r) The second is magnetic induction, in which a voltage is induced in a loop of wire if the total magnetic flux linking that loop changes. The voltage induced in the wire loop (in SI units) is: V = d(flux)/dt.
What Magnetic field strengthcalled?
In the SI system magnetic field strength is measured in Teslas, and 1 Tesla = 1 Weber/m2. These SI units replace the previously used units Gauss and Maxwell, with 1 Tesla = 104 gauss, and 1 Weber = 108 Maxwell. the subunits of the Weber are Volts x seconds, so the Tesla is ( Volts x Seconds)/m2.Further insight can be obtained from the relation Change of flux of 1 weber/sec produces an EMF of 1 volt, which ties in with above subunits of the Weber.See Wikipedia for the Tesla and Weber for further readingThe above answer is incorrect.The above answer correctly describes flux density (symbol B), not magnetic field strength (symbol H).Magnetic field strength is defined as magnetomotive force (mmf) per unit length, and is measured in amperes per metre (A/m). Magnetic field strength used to be called 'magnetising force'.
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. ..."
Why is the Gauss used instead of the Tesla to describe the strength of a magnetic field?
Both units are used to measure magnetic flux density. The tesla is the SI unit of measurement, whereas the gauss is an obsolete, cgsA, unit.
What unit of measurement is used to measure an electromagnetic field and what instrument is used to measure that?
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.
What are the units in getting the mass?
Mass can be worked out by using the following formula: Mass=gravitational field strength divided by weight, of course the units you use are grams, kilograms and tonnes.
Will the acceleration due to gravity equals to magnetic field when a bar magnet falls through a metal ring?
Please note that a magnetic field is not measured in units of acceleration (or the equivalent force / mass), like gravity is. What exactly happens when a bar magnet falls through a metal ring will depend on the details of the situation - for example, how strong the magnetic field is, and the mass of the bar magnet.
