Hello Dinu,

The induced voltage is coming up as negative becuase the current excitation direction specified is opposite to the one in which the current would flow . 

Beucase of the magnetic field B the induced current in the coil would be in anticlock wise direction but the assigned direction is in clock wise direction. In order to represet this the induced voltage is coming up as negative component.
