摘要：

The paper concentrates on the optical fibre sensors of electric current intensity. The specially elaborated glasses with high values of refractive indices were investigated in the prepared testing stand. The glasses have possessed the refractive index values n in the range 1.6 <= n <= 2.2. For the glasses the values of the Verdet constants for two waveguides: lambda(1) = 635 nm and lambda(2) = 1550 nm were determined. The obtained results showed that the elaborated on the base of new glasses optical fibres are much more sensitive on the action of magnetic field than the silica fibres.
