Magnetic flux with non-uniform magnetic field Physics Forums. Magnetic field and work гћmagnetic force is alwaysperpendicular to velocity when b is non-uniform, then there is net force. can be shown that the direction of this force is such that magnetic dipole moment is attracted to the region of high b. гћmagnetic force does no work. but when two bar magnets are attracted to each other, there must be work done by b. something is not right here, suppose there is a uniform magnetic field b in a region of space. letвђ™s discuss the magnetic force on an electric charge q in this region of space. first of all it is found that if the charge is at rest there is no magnetic force acting at all. furthermore, if the charge does move, but has its velocity along the magnetic field direction (deter-mined, e.g., by a compass needle) then there is.

### Effect of non-uniform magnetic field on biomagnetic fluid

What is uniform magnetic field? Quora. Magnetic field is the magnetic effect of electric currents and magnetic materials. the magnetic field at any given point specified by both direction and a magnitude. so uniform magnetic field has equal amount of force or magnetic force in both side of the object while the non uniform magnetic field has one of the object exert more than the other, magnetic flux and electromagnetic induction with non-uniform magnetic fields. 2 magnetic flux in a nonuniform field so far, we have assumed that the loop is in a uniform field. what if that is not the case? the solution is to break up the area into infinitesimal pieces, each so small that the field within it is essentially constant. then: d b daо¦ = в‹…m r r m area of loop о¦ = в‹…в€« b da r r.

A new technique is proposed for nmr image restoration from the influence of main magnetic field non-uniformities. this technique is applicable to direct fourier nmr imaging. the shape of a magnetic fluid bridge between a horizontal ferrite rod of circular cross-section and a horizontal plate above the rod in a vertical applied uniform magnetic field is studied.

Suppose there is a uniform magnetic field b in a region of space. letвђ™s discuss the magnetic force on an electric charge q in this region of space. first of all it is found that if the charge is at rest there is no magnetic force acting at all. furthermore, if the charge does move, but has its velocity along the magnetic field direction (deter-mined, e.g., by a compass needle) then there is three points are arranged in a uniform magnetic field. the magnetic field points into the screen. 1) a positively charged particle is located at point a and is stationary. the direction of the magnetic force on the particle is: a) right b) left c) into the screen d) out of the screen e) zero the magnetic force is given by f qv b r r r = г— but v is zero. therefore the force is also zero

Recently, the authors have found another method to realize the famous hypothesis. a non-uniform magnetic field can provide a one-way channel for thermal electrons ejected by an electromagnetic source adjacent said liquid crystal layer, said electromagnetic source operative to generate a spatially non-uniform magnetic field acting on said liquid crystal layer, said magnetic field being dynamically variable on a basis of electrical current applied to said electromagnetic source, such that optical properties of said device are controllable.
