Is magnetic field strength a scalar? What causes a magnetic field? What is Earth's magnetic field made of? How strong is the magnetic field in an MRI? What kind of magnetic field is produced by a solenoid? Is gravity a magnetic field?
magnetic flux density,magnetic intensity,magnetic induction field intensity,field strength- the vector sum of all the forces exerted by an electrical or magnetic field (on a unit mass or unit charge or unit magnetic pole) at a given point in the field ...
Development of A SQUID-Based Low-Field NMR/MRI System In the case of most physiological tissues, longitudinal relaxation time (T1) depends on the applied magnetic field strength, and the T1-contrast between di... M Miyamoto,J Hatta,D Oyama,... - 《Physics Procedia》 被引量: 8发表: 2012...
Thus neither T1 nor T2 will be much affected, at least over the range of fields used for MR imaging.For protons in molecules with intermediate or low mobility, however, shifting the magnetic field to a higher value may significantly decrease the fraction of these protons able to interact at ...
Increasing the number of windings is probably the easiest way to increase the strength of an electromagnet. Since mmf = nI, doubling the number of windings doubles the strength of the magnet. It's fine to wrap the wires in layers around the solenoid core. The magnetic field is unaffected ...
