35. An electromagnet is used to separate magnetic and non-magnetic objects as shown in the picture below.The list of objects to be separated is as follows :rubber shoe ceramic mug iron rod styrofoam cup steel spoon nickel coin aluminium foil copper wire(a) Classify the objects in the classif...
Metals can be magnetic and non-magnetic. The magnetic ones will produce a field around them, usually described as “ferromagnetic.” These metals are not magnetic by themselves in their natural state. Still, they can be attracted to objects that produce magnetic fields. Once magnetized, these me...
This coating source may also be used efficiently and effectively with sputter target materials having properties which range from nonmagnetic to highly ferromagnetic. Use of an electromagnetic coil with a widely adjustable energizing current, rather than permanent magnets, allows a wide range of magnetic...
In the foregoing discussion themagnetic fieldwas assumed to be uniform; this is not realistic. The Earth's magnetic field, to lowest order, is a dipole field that changes in direction and magnitude, both along and across the field lines. Charged particles will drift with anonuniform magnetic ...
The present paper is devoted to the study of the event horizon properties of spacetime around a regular nonminimal magnetic black hole (BH), together with dynamics of magnetized and magnetically charged particles in the vicinity of the BH. It is shown th
Various astrophysical objects and processes have been proposed by numerous authors as sources of cosmic ray electrons. However, it is generally believed and very likely that apart form discrete sources that inject electrons into the interstellar space the bulk of the cosmic ray positrons presumably ar...
dedicated to the development of the analog of Morse theory for the closed 1-forms -- multivalued functions and functionals -- on the finite - and infinite-dimensional manifolds ({\bf Morse-Novikov Theory}).The notion of ``Multivalued action'' was understood and ``Topological quantization of ...
2). The non-collinear character in space and time of the magnetization is also observed when the atomic displacements are all linear. For instance, for an acoustic phonon with vector q = M at which Se atoms move along q and W atoms vibrate in the perpendicular direction to the plane...
Lorentz reciprocity is a fundamental characteristic of the vast majority of electronic and photonic structures. However, non-reciprocal components such as isolators, circulators and gyrators enable new applications ranging from radio frequencies to optic
2.3.2 Magnet-type EMA material in static magnetic field and LF field The static magnetic field and LF field can exert physical forces on both metallic objects and moving electric charges. Exposed to the static magnetic field, the charged cells and particles in the blood can be accelerated or...
