Calculation of the mutual induction between coplanar circular surface coils in magnetic resonance imaging.
The induced current in a coil due to the presence of alternating currents in an adjacent coil is calculated here for a case of two similar and coplanar, circular coils. By using an overlapping configuration, the mutual inductance is nullified as is predicted theoretically and confirmed experimentally.
