A wire is carrying a
+rcc(bq)w y-xgr.nf s*abz7 /y pmgs* qi4m;( current $I$ is placed in a region of uniform magnetic field $B_1$. The magnitude of the magnetic field is $B$, and its direction is into the page. The force acting on the wire is $F$, as shown in the diagram.
The wire, carrying the same current $I$, is now placed with the orientation shown into another region of uniform magnetic field $B_2$. The magnitude of the magnetic field is $B$, and its direction is out of the page.
What is the correct direction and magnitude of the force acting on the wire in field $B_2$?
