Abstract
The invention concerns a nuclear resonance well logging tool for insertion into a borehole with a permanent magnet which is magnetized perpendicularly to its axis and with means to transmit and to detect high frequency signals whereby the transmission and detection coils are orthogonal. The arrangement is configured for CW operation. The permanent magnet or the transmission and detection coil arrangement may rotate around the axis in order to modulate the nuclear resonance signals.
