A conducting wire slides with constant speed of 1 m/s on a bent L shaped metalic rail. The angke between the wire and the rail is 45 deg and it remains constant during the whole motion of the wire. Perpendicular to the plane of the rail acts a magnetic field B=0.2 T in the X direction (Into the paper). At the beginning of the wire's motion - the point A, which is at the center of the wire, is 1m away from point C. What's the magnetic flux as function of time? Why can't I say that the wire moves in the positive x direction (to the right) according to: x(t)=x0+vo,x*t, and the wire moves in the positive y direction (upwards) according to: y(t)=y0+vo,y*t where x0=y0= AC/sin45 and vo,x=vcos45, vo,y=vsin45?
