WebDotted path represents the initial magnetization from the metal's virgin state. When a ferromagnetic object is removed from the external applied field (i.e., taken out of the scanner), it will in general not fully return to its previous unmagnetized state but retain some residual magnetization (known as remanence ). WebVertical bore scanner showing main (Bo) and RF (B1) fields. M is initially aligned with Bo but will be tipped away by the action of B1, precessing at the resonance frequency. Continued application of the B 1 field results in progressive tipping of the net magnetization away from its initial alignment with B o.
