Markscheme
B lies in magnetic field of A OWTTE ✓
Explained use of appropriate rule together with drawn indication of rule operating in this case ✓
To show that force on B is to left and in plane of paper ✓
OR
Magnetic field lines of B merge with those of A to give combined field line pattern ✓
Sketch of combined pattern to show null point somewhere on line between wires. ✓
Wires will move to reduce stored energy and this is achieved by moving together so force on B is to left ✓
