Abstract
An apparatus includes a plurality of particles, wherein each particle contains a plurality of magnetizable (for example, ferromagnetic) and ferroelectric materials in fixed physical relationship (for example, physical contact) with one another. A method and apparatus measure magnetic fields arising from or within the plurality of particles.
Claims17
An apparatus for measuring electric fields in a structure, the apparatus comprising:
- a plurality of particles, wherein each particle contains component materials with magnetizable and ferroelectric properties, and the component materials are in fixed relative positions to one another;
- and
- an instrument sensitive to magnetic fields or to changes of magnetic fields, wherein the instrument is configured to detect change in magnetizations of one or more magnetizable components of the plurality of particles when one or more ferroelectric components in the plurality of particles rotate when exposed to an externally-applied electric field.
A method of measuring electric fields in a structure, the method comprising:
- introducing a plurality of particles into or upon the structure, each the particle containing component materials with magnetizable and ferroelectric properties, wherein the component materials in fixed relative positions to one another;
- and
- detecting, using an instrument sensitive to magnetic fields or to changes of magnetic fields, a change in magnetizations of one or more magnetizable components of the plurality of particles when one or more ferroelectric components in the plurality of particles rotate when exposed to the electric fields within the structure.
