Near the Wire: The magnetic field is most intense close to the carrying conductor. Here, the field lines are densely packed, indicating a stronger magnetic effect. Away from the Wire: As one moves further from the wire, the magnetic field’s intensity diminishes. This decrease in strength is...
A flaw is pointed out in the justification given by Charitat and Graner (2003 Eur. J. Phys. 24 267) for the use of the Biot-Savart law in the calculation of the magnetic field due to a straight current-carrying wire of finite length....
magnetic field lines are directed from the South Pole to the North Pole. Thus, we can say that magnetic field lines form a closed curve. They can never intersect with each other.
Lines of the magnetic field produced by a long straight wire carrying a current are:A.radially inward toward the wireB.radially outward from the wireC.circles that are concentric with the wireD.in the direction of the current的答案是什么.用刷刷题APP,拍照
XV. A note on the magnetic field of a rectilinear circuit and the attraction of a straight wireThis paper presents a summary of all catch-comparison gear tests performed between 2002 and 2006 with Nordmre-type sorting grids in the Swedish Nephrops trawl fishery in the Skagerrak and Kattegat....
direction of the magnetic field? The greater the magnetic force experienced by the test magnet, the stronger the magnetic field strength. the direction of the magnetic field at a point is taken as the direction that a north pole would tend to move if it were at that point ...
作者: FJ Lowes 摘要: MCCAIGhas suggested that a shape factor might be involved in determining the force on a current-carrying wire in a magnetic field when there is a permeability contrast between the wire and its surroundings. DOI: 10.1038/246208A0 收藏...
Current-induced magnetic fields: (a) a straight wire and (b) a solenoid. The magnetic field of a solenoid is similar to that of a permanent magnet (shown earlier in Figure 17.1). This is not a coincidence. An electron orbiting around the nucleus of an atom is a form of charged ...
A long straight wire carrying a current is the simplest example of a moving charge that generates a magnetic field. The force a charge feels when moving through a magnetic field depends on the right-hand rule. The direction of the magnetic field due to moving charges also depends on the ...
The magnetic susceptibility (χ) of a material is defined as (4.12)χ=M/H The magnetic induction (B) is related to the field intensity (H) as (4.13)B=μH where μ is characteristic of a medium and is known as magnetic permeability. The relative permeability is defined by the ratio of...
