Ans: It is a line in a magnetic field which indicates the direction along which the magnetic force acts. It is a continuous curve in a magnetic field such that the tangent at any point on it gives the direction of the resultant field at that point.

The magnetic scalar potential is, in general, discontinuous across a surface carrying a surface current density. It is its normal derivative that is continuous. The scalar potential provides an elegant representation of the fields in free space regions surrounding current loops.

A uniform magnetic field is represented by equally-spaced, parallel straight lines. These lines are continuous, forming closed loops that run from north to south, and looping around again.

This is the magnetic field effect of any permanent magnet: Continuous loops begin at the north pole, point away and wrap back around to the south pole. This magnetic field protects us on Earth from radiation released from the sun during solar storms that is deflected away from the Earth by its magnetic field.

dipole fields that vary appreciably on the atomic scale. The process of averaging the microscopic quantities to obtain the macroscopic description on magnetic fields in matter will be discussed in the second part of EM. The result of this averaging is a macroscopic magnetic field B which obeys the same equation ∇⋅=B 0 (6.1)

ACGIH threshold limit values for continuous exposure to static magnetic fields Abbreviations used in this table: G – Gauss; a unit of magnetic field intensity, equal to 0.0001 Tesla mT – millitesla T – Tesla; magnetic field strength is measured in Tesla TWA – time weighted average Note: 1 Gauss (G) = 0.1 millitesla (mT)

This implies that the number of magnetic field lines entering a closed surface is equal to the number of field lines leaving the surface. That is, there is no source or sink. In addition, the lines must be continuous with no starting or end points. In fact, as shown in Figure 13.2.1(b) for a bar magnet, the field lines that emanate from the ...

Answer (1 of 2): Magnetic field is definitely continuous. To quote from the Wikipedia page on magnetic field: "Magnetic field lines are like the contour lines (constant altitude) on a topographic map in that they represent something continuous, and a different mapping scale would show more or fe...

Magnetic fields are commonly used to control flows in metal processing, MHD pumps, plasma and fusion technology, to name a few [1]. Continuous casting is one process using different types of magnetic fields in the mold to minimize defects in the final product [2]. When

Magnetic fields may be represented by continuous lines of force or magnetic flux that emerge from north-seeking magnetic poles and enter south-seeking magnetic poles. The density of the lines indicates the magnitude of the magnetic field. At the poles of a magnet, for example, where the magnetic field is strong, the field lines are crowded together, or more dense.

Experimental results show that compared with the control group (CK), the alternative magnetic field continuous treatment (AMCT, B = 20 Gs, f = 60 Hz) group and the alternative magnetic field intermittent treatment (B = 20 Gs, f = 60 Hz, t = 12 h) group both obviously have a lower respiration rate, polyphenol oxidase (PPO) activity, and degree ...

11/28/2004 Magnetic Boundary Conditions 2/6 Jim Stiles The Univ. of Kansas Dept. of EECS First, let's write the fields at the interface in terms of their normal (e.g.,H n()r ) and tangential (e.g.,H t(r)) vector components: Our first boundary condition states that the tangential component of the magnetic field is continuous across a boundary.

The Tangential Magnetic Field* is Continuous In other words, The total B-field in the plane of the interface is continuous. Here, all B-fields are in the xy-plane, so we take the x-components: Reflection and Transmission for Perpendicularly Polarized Light

Interface conditions describe the behaviour of electromagnetic fields; electric field, electric displacement field, and the magnetic field at the interface of two materials. The differential forms of these equations require that there is always an open neighbourhood around the point to which they are applied, otherwise the vector fields and H are not differentiable.

Unlike electric field lines, magnetic field lines are continuous. Magnetic field lines are close together in regions of space where the magnitude of the magnetic field is weak, and they are father apart in regions where it is strong. Magnetic field lines point in the direction of the magnetic force acting on a charge. Magnetic field lines can ...

Magnetic field lines are continuous, forming closed loops without a beginning or end. They are directed from the north pole to the south pole. The last property is related to the fact that the north and south poles cannot be separated. It is a distinct difference from electric field lines, which generally begin on positive charges and end on ...

Magnetic lines form continuous closed loops because magnetic monopole does not exist in nature. We always find magnetic poles - North and South pole which are coupled together in such a way that field lines originating from one pole ends at the another loop, forming a closed loop.

The magnetic system of the HGMS produces a uniform mag-netic field in the process area. To generate the necessary magnetic field gradient, a matrix of magnetic material with a structure such as expanded metal or steel wool is inserted. A high magnetic field gra-dient is hereby created around the filament of the matrix. The sharp

Magnetic field lines represent continuous curves that originate at the north pole of the magnet and end at the south pole.While we can find electric monopoles in the form of charged particles, we have never observed magnetic monopole. Instead, magnets exist only in …

Using ground-based observatories, we provide continuous records of magnetic field variations; disseminate magnetic data to various governmental, academic, and private institutions; and conduct research into the nature of geomagnetic variations for purposes of scientific understanding and hazard mitigation.

Answer: Magnetic field lines represent continuous curves that originate at the north pole of a magnet and end at the south pole. Inside the magnet they travel from the south pole to the north pole. As isolated magnetic poles or monoploes do not exist; the smallest source of magnetic field is a m...
