QUESTION 1 In this experiment we will observe the Magnetic Force acting on a current carrying wire. In our case. the B field is perpendicular to the current flow. What is the general relation for the strength of the magnetic force when B and the current flow are at an angle? OFg= IlBsin (9) OF== IvBcos(8) OF= IlBeo= (8) OF= 1Bsin(9) QUESTION 2 Which of these is correct about the values "d" and "x" we will meaure? O x and d are directly observed and have units of Tesla O x and d are both directly observed postions O x is a calculated difference of two positions and d is an observed position O x is an observed position and d is a calculated difference of two positions QUESTION 3 You will do two sets of power supply current versus wire displacement measurements, one using 20 gram mass and one using a 10 gram mass. Which of these is true about these sets of measurements? The 10 gram set will use a maximum I (current) of 0.5 Amp; the 10 gram set will use a maximum I (current) of 0.86 Amp O The 10 gram set takes larger increments in I (current) because the wire will the end of the scale at a lower current than with the 20 gram mass O The 10 gram set takes smaller increments in I (current) because the wire will the end of the scale at a lower current than with the 20 gram mass The 10 gram set takes twice as many values of I (current) than the 20 gram set QUESTION 4 In the plots of x versus I, the y-intercept of the plot will be which of these? lo. the starting current of the wire O d, the displacement of the wire O B, the magnetic field of the neodymium magnet O xor the starting position of the wire QUESTION 5 The slope of your x versus | plot is which of the following? O the slope is proportional to (but not equal to) B, the field of the neodymium magnets O the slope is d, the displacement of the current carrying wire O the slope is B, the field of the neodymium magnets O the slope is strongly dependent on the earth's magnetic field.
