A magnetic field is described by magnetic lines of?
force that represent the direction in which a magnetic object would move if placed in the field. These lines form a pattern that helps to visualize the strength and direction of the magnetic field. The density of the lines indicates the strength of the magnetic field at a particular point.
What is the difference between magnatic field strength and pole strength?
Magnetic field strength refers to the intensity of magnetic field lines in a given area, measured in units of tesla or gauss. Pole strength, on the other hand, refers to the strength of the north or south pole of a magnet, which determines how strong the magnetic field is at that pole. In simpler terms, magnetic field strength is the overall intensity of the magnetic field, while pole strength specifically refers to the strength of individual poles on a magnet.
What is the unit to measure the strength of a magnetic field?
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.
How do you calculate magnetic flux density?
'Magnetic field strength' (symbol: H) is defined as 'the magnetomotive force, per unit length, of a magnetic circuit'. In SI, it is expressed in amperes per metre (A/m), which is often spoken as "'ampere turns' per metre".It's equation is: H = (IN) / lwhere:H = magnetic field strength (ampere per metre)I = current flowing through coil (amperes)N = number of turns in coill = length of magnetic circuit
How do you reduce the strength of magnetic field?
To reduce the strength of a magnetic field, you can increase the distance between the magnet and the object affected by the field, use a material that can shield or redirect magnetic fields (like mu-metal), or use a magnetic field cancellation system that generates an opposing magnetic field to nullify the original field.
What is the relationship between magnetic energy density and the strength of a magnetic field?
The magnetic energy density is directly proportional to the strength of a magnetic field. This means that as the strength of the magnetic field increases, the magnetic energy density also increases.
Can density of magnetic field send parallel to infinity?
No, the density of a magnetic field cannot be sent parallel to infinity. The magnetic field strength decreases with distance from its source, meaning it will weaken as it spreads out from a source.
What is the limit for magnetic field developed for a DC machine?
The magnetic field used in machines is quantified in terms of its flux density (symbol: B), expressed in teslas. The flux density is established by the magnetic field strength (H), expressed in amperes per metre, set up in the field windings.As the magnetic field strength increases, the flux density increases until it reaches saturation. This is the point when the magnetic domains within the magnetic circuit are all aligned. At this point, any further increase in magnetic field strength will fail to increase the flux density.So saturation of the magnetic circuit limits the flux density of the field.
What is the relationship between the surface current density and the magnetic field on a current sheet?
The surface current density on a current sheet is directly proportional to the magnetic field it produces. This means that as the surface current density increases, the strength of the magnetic field also increases.
Can a magnetic force pass through gases?
Yes, magnetic fields can pass through gases. However, the strength and interaction of the magnetic field with the gas will depend on factors such as the type of gas, its density, and the strength of the magnetic field.
A magnetic field is described by magnetic lines of?
force that represent the direction in which a magnetic object would move if placed in the field. These lines form a pattern that helps to visualize the strength and direction of the magnetic field. The density of the lines indicates the strength of the magnetic field at a particular point.
What is the diagram of a magnetic field and how does it illustrate the direction and strength of the magnetic field lines?
A magnetic field diagram shows the direction and strength of magnetic field lines around a magnet or current-carrying wire. The lines indicate the direction a compass needle would point if placed in the field. The density of the lines represents the strength of the magnetic field, with closer lines indicating stronger fields.
What is the relationship between neodymium and magnetic field strength?
Neodymium is a type of rare earth magnet that is known for its strong magnetic properties. When neodymium magnets are used in a magnetic field, they can significantly increase the strength of the field due to their high magnetic flux density. This means that neodymium magnets can enhance the overall magnetic field strength when placed within it.
How can you tell from the pictures where the magnetic fields are the strongest?
You can tell where the magnetic fields are strongest in a picture by looking for areas where the magnetic field lines are closest together, indicating a higher field strength. The density of the field lines represents the strength of the magnetic field.
Do magnetic field lines close together indicate a weaker magnetic field?
No, magnetic field lines close together indicate a stronger magnetic field, while magnetic field lines farther apart indicate a weaker magnetic field. The density of field lines represents the strength of the magnetic field in that region.
What does crowding of magnetic field lines indicate?
Crowding of magnetic field lines indicates a stronger magnetic field in that area. The density of magnetic field lines is directly related to the strength of the magnetic field in a particular region. This can be observed in areas near magnetic poles or strong magnets.
Do field lines need that are close together indicate a weaker magnetic field?
No, field lines that are close together indicate a stronger magnetic field, not a weaker one. The density of field lines represents the strength of the magnetic field in that region.
