Real time display with the ferrolens of homogeneous magnetic fields

In our previous published research we have studied the applications of ferrolens for observation and qualitative analysis non-homogeneous magnetic fields. Latest developments over last few years increased multifold sensitivity this device allowing it to display fields as low 10mT in strength therefore is possible now observe also homogeneous (i.e. straight parallel flux lines uniform density space) field existing inside air solenoids between N-S poles two attracting separated permanent magnets. We present analyze herein these novel observations with a potential new application device. The can projected on from distance without needing be physical contact source. Experiments were carried out demonstrate capabilities nanomagnetic viewer, real-time scientific tool. compare geometry condensed matter ferromagnets that electrical solenoids. Specifically, magnets at well Helmholtz coils total single dipole observed using latest generation very sensitive ferrolens. unique feature magneto optic fluid thin film discrete macroscopic field. Also show how used detect qualitatively symmetry center non ideal
