A bipolar lateral magnetotransis- tor comprises a semiconductor substrate (1) with conductivity of a first type and the following regions formed on the upper surface of the substrate (1) in consecutive order, and spaced apart: a first base region (2) with conductivity of the same type as the substrate (1); an inject region (3) with conductivity of a second type; a collector region (4) with conductivity of the second type; and a second base region (5) with conductivity of the first type, there being a second inject region (6), having conductivity of the second type, disposed on the other side of the first base region (2). A magnetic field B in direction 7 influences minority carriers injected from regions 3, 6 and hence the collector current. An output signal is derived from between the collector 4 and base 5. IMAGE
