Magnetic field lines are the lines in a magnetic field the tangent of which at any point will give the field direction at that point and its density gives the magnitude of the field. The magnetic field intensity depends on the number of magnetic field lines. The lines are higher at the po...
Electromagnetic coils are typically solenoid-shaped large inductors. The current passing through the electromagnets generate magnetic fields. This magnetic field can be adjusted by controlling the current amplitude and direction applied to each coil. Combinations of individually addressable coils can be used...
stray magnetic field 𝑯𝑠𝑡𝑟Hstr (formerly denoted as the external field 𝑯H) given by pair of quasi-magnetic monopoles, each located at the end of the sample and mutually separated by a distance 𝑙=2|𝒓′|l=2r′, the following equation was derived based on the Formula (13...
The length of a solenoid was greater than the diameter of a tightly winded coil, whose translational and rotational symmetry was considered. An electromagnet, shown in Figure 1B, essentially consists of an iron core bent at its end, which was designed to enhance the field strength by means ...
This is the direction a compass needle points to as it aligns with the Earth's magnetic field. What are magnetic poles? Magnetic poles are regions at the end of a magnet where the magnetic field is strongest. The north magnetic pole on Earth is located in the Arctic Circle. The south ...
To detect the magnetic droplets, the same as previous experimental setup section, the magnetometer signal was locked on the resonance frequency of the stray magnetic field (B0) of the solenoid and the variation of light intensity was recorded. Results and discussion Formation of the spike-like sig...
When a magnetic material is subjected to an external magnetic field (H) it gets magnetized. The magnetization (M) of a material is defined as the magnetic moment per unit volume (V). (4.11)M=m/V The magnetic susceptibility (χ) of a material is defined as (4.12)χ=M/H The magnetic...
The conversion formula of Tesla and Gauss is: 1 Tesla = 10000 Gauss 4)Magnetic Gradient: The rate of change of magnetic field strength or the rate of change of magnetic field density within a unit distance (for example, 1 cm). The degree of inhomogeneity of the mag...
In addition, “diamagnetic field correction” when the M-H loop is measured in the longitudinal direction of the magnetic tape MT is not performed. (Squareness Ratio) The squareness ratio S1 of the magnetic layer 43 in the vertical direction of the magnetic tape MT is preferably 65% or more...
constant flux distribution at all magnetic field strengths. The magnet poles are shaped such that the surfaces thereof conform to an exponential function. Magnetic shunts are located at a predetermined spacing from the entrance and exit end of the analyzing sector to locate the magnetic field ...
