The force acting on a straight wire of length 10 cm carrying a current of 4 A in the +Z direction due to a uniform magnetic field is (-2i^{\^}+2j^{\^}) N. If the wire is rotated so that itcarries a current in +ve X-direction. the force on the wire becomes (-2\sqrt2 j^{\^}+2k^{\^}) N. The strength of the magnetic field is _____ T.
