The engineering of a novel intra-operative MRI system is described. A movable, 1.5 Tesla MRI magnet was placed in a neurosurgical operating room without affecting established neurosurgical procedure. The system allows fast, high-quality MR intra-oper

The use of copper-clad steel wire to construct solenoids for generating intense magnetic fields is discussed. The proportion of steel to copper is used to vary the strength to conductivity ratio enabling an optimum coil to be designed for which stres

Measurements have been carried out of the strain exerted on the conductor of a copper-wire-wound coil used to produce intense pulsed magnetic fields. The strains, measured using resistance strain gauges, were used to calculate the azimuthal and axial

In the generation of intense magnetic fields using copper wire‐wound solenoids an upper field limit is often imposed by Lorentz forces in the conductor. The use of materials such as 2% Be‐Cu alloy increases the maximum stress permitted fields, bu
