Test Your Understanding of Section 27.6 The figure at right shows a top view of two conducting rails on which a conducting bar can slide. A uniform magnetic field is directed perpendicular to the plane of the figure as shown. A battery is to be con- nected to the two rails so that when the switch is closed, current will flow through the bar and cause a magnetic force to push the bar to the right. In which orientation, A or B, should the battery be placed in the circuit? Which orientation? B A Switch Conducting bar X Conducting rails X X XXX X xx F X X X X B X X

Two wires lie in the plane of the page (figure1). Wire 1 carries conventional current to the left, and wire 2 carries conventional current to the right. Choose from the following possible directions (figure 2) to answer the question: what is the direction (a – h) of the magnetic force that wire 1 exerts on wire 2?
Show all working explaining detailly each step. Imagine you were provided with: 3 grey cardboxes labelled P, Q, and R, fixed to the surface of the a table using cello tape, a plotting compass. Using a plotting compass and three black boxes labeled P, Q, and R, one of them contains a ferromagnetic material, another one contains a magnet while the third one contains a non-magnetic material. Without opening them up, run tests on them and distinguish between them, using a plotting compass. Give a brief outline of your procedure, Observation/results, Calculations, Inference, Conclusion, highlighting any precautions you have taken to improve on the accuracy of your results. Hence give pictorial images of your set-up & diagram
