Weber
 
(Wb) The SI unit of magnetic flux.
Definition: The rate (per unit of time) in which something crosses a surface perpendicular to the flow. If the something is a magnetic field, then the magnetic flux across a perpendicular surface is the product of the magnetic flux density, in teslas, and the surface area, in square meters.

Wires (MRI Safety Risk)MRI Resource Directory:
 - Safety -
 
Pacemaker lead wires, ECG, and plethysmographic cables can also as surface-coil connections act as antennae. Usually the materials of such wires are not ferromagnetic.

MRI Safety Guidance
Gradient and radio frequency fields may induce current into these wires and thus cause fibrillations and burns. This presents a risk to the patient and must be eliminated before the examination. The risk of heating during the MRI scan is dependent on the length and the material of these wires as well as the used field strength. If these wires are outside the RF field there is no risk of heating to expect.
