Magnetic field detector
A magneto-optic cell comprising a composition responsive to magnetic fields. The composition comprises a ferrofluid and metal flakes which align with the ferrofluid in response to magnetic lines of force and along the magnetic lines of force. Detection of the presence of a magnetic field is thereby...
