Gradient of a magnetic field
WebJun 19, 2016 · A gradient is the linear variation of the magnetic field strength along a certain direction. Under a magnetic field gradient, the NMR frequency depends on the position. If we measure the spectrum of a sample under a gradient, the spectrum is a one-dimensional image, or profile, of the sample. This is how the NMR MOUSE, one of … WebThe simplest type of magnetic field is a constant field. A charged particle in a constant field executes a circular orbit, with radius ρand frequency ω. B v ρ To find the direction of the force on the particle, ω use the right-hand-rule. Force on a Particle in a Magnetic Field What would happen if the initial velocity had a component in
