1 Fig. 1.1 shows two identical cylindrical metal conductors P and Q, each of length and cross-sectional area A. Fig. 1.1 L Q P The conductors are placed parallel to each other. The perpendicular distance from the midpoint of P to point X is p. The perpendicular distance from the midpoint of Q to point X is q. The two conductors are electrically connected in parallel. This parallel combination is connected in series to a power supply and a resistor. The potential difference V between the ends of P is the same as the potential difference between the ends of Q. The magnetic flux density at X due to the currents in the conductors is B. It is suggested that B is related to p by the relationship B = Lp where Y and Z are constants. Plan a laboratory experiment to test the relationship between B and p. Draw a diagram showing the arrangement of your equipment. Explain how the results could be used to determine values for Y and Z. In your plan you should include: the procedure to be followed the
