Abstract
A magnetic transducer is disclosed which utilizes the magnetostrictive effect for creating an easy axis of magnetization in the longitudinal axis of a magnetic wire having a high cobalt content by bending the wire, which is then placed in a non-magnetic hollow tube. This tube is placed in the axis of a detection coil. The application of a magnetic field, alternately in one direction and the other in the longitudinal axis of the assembly creates a flux variation due to the magnetization change in the easy axis. The pulses detected have a high amplitude and a low rise time.
