The paper presents results of investigations of 
the process of the creation of a diamagnetic cavity by 
a laser-produced plasma in a strong transverse magnetic 
field of 10 T in induction. The plasma was produced from 
a flat, teflon target by an Nd laser of 5 J in energy and 
about 1 ns in pulse duration. The investigations were carried 
on by means of a three-frame interferometry and a non-contact 
magnetic probe, a so called remote magnetic probe (RMP). 
For the needs of this work, we developed a methodology 
for the measurement of the dimensions of the cavity during 
its expansion by means of the RMP, taking into account 
the plasma expansion geometry that is specific to flat 
targets. The dynamics of the process of creation of the 
diamagnetic cavity, its shape and dimensions have been 
determined. A very good consistency of dimensions of the 
diamagnetic cavity and plasma boundary in their quasisteady 
state, obtained with both diagnostics, allows us to apply 
the RMP method not only for the investigation of diamagnetic 
properties of various laser-produced plasmas, but also 
for the evaluation of their initial kinetic energy and 
its transformation in magnetic field.</jats:p
