An alternating magnetic field is applied. Its amplitude is so large that the magnetic hysteresis is driven into the saturation region. The method may also be used in determining the associated force. In which c
We take the magnetic field to be uniform over the rectangular loop, which has width w and height l. First, we note that the forces on the top and bottom segments are vertical and, therefore, parallel to the shaft, producing no torque. Those vertical forces are equal in magnitude and ...
A tightly wound 100 turn coil of radius10cmis carrying a current of1A. What is the magnitude of the magnetic field at the centre of the coil? View Solution Free Ncert Solutions English Medium NCERT Solutions NCERT Solutions for Class 12 English Medium ...
As a source for the selection field, four small rectangular NdFeB magnets with opposing magnetization directions were stably held on the sides of the device by holes cut into the PDMS (Fig. 2B). This arrangement pro- duced a field-free region coinciding with the central chamber of the ...
Torque arises when there is a difference in forces acting on opposite sides of the loop. For example, if the top segment of a rectangular loop is pushed out of the page while the bottom segment is pushed into the page, the loop will begin to rotate about an axis. The torq...
We have developed a layout consisting of a nanoscale, elliptic magnetic structure (''nanopillar'') and two micronscaled, rectangular magnetic elements (''polarizers'') as shown in figure 1. Both, the central pillar and the surrounding polarizers are fabricated from CoFe at a thickness of 8 nm...
Okay, so, the magnetic field lying(parallel) to the plane of the coil is confusing me quite a bit. Usually, in this kind of problem, we have a magnetic field directed perpendicularly to the plane. Considering this orientation of the field, wouldn't the torque on this sort of "elementary...
an electrically conducting coil on the solar panel adapted to carry current for generating a magnetic field for interacting with an external magnetic field to adjust the attitude of the spacecraft, the coil being electrically connected to a voltage ground; ...
10. Apparatus as set forth in claim 9, wherein said generating means includes said first pole and further comprises an excitation coil wound around said first pole for generating a magnetic field in said pole, said magnetic field being coupled into said shaft through said axial air gaps and ...
parallelogram face each other with a gap interposed therebetween, a first coil concentrically wound around the magnetic material strip, amagnetic core disposed outside of the magnetic material strip in no contact therewith through a space, and a second coil wound around the magnetic material strip....
