Physics students, wanted to investigate the forces of attraction (F) between two parallel conductors carrying currents li and l2 (also known as Ampere's Law) The students noticed that as the length of the parallel conductors (/) was increased the force of attraction between the conductors (F) also increased. The data collected is in the |L= SA conductor 1 average separation (d = 0.50m) table: conductor 2 Length, / (m) Force, F (x 10-5 N) 12= 5A 1.00 9.00 1.20 10.8 1.40 12,5 1.60 14.2 1.80 16.2 (iii) On the grid plot the force and length values from the table. (iv) Draw the line of best fit (v) Find the slope of the line of best fit. (c) Use the slope calculated and the Ampere's Law equation to determine the experimental value of the magnetic force constant, k.
The drift speed of charge carriers in a conductor carrying current / is ngA where n is the number of mobile charge carriers per unit volume, q is the magnitude of the charge on each carrier, and A is the cross-sectional area of the conductor. The transmission line has a diameter of 2.00 cm so that its radius is r= 1.00 cm = 1.0 x 10 m and so that its cross-sectional area is A = nr? - n(1.0 x 10-2 m)² = n x 10-4 m2. In metallic conductors, the mobile charge carriers are electrons, each with a charge of magnitude q- e. We are given the density n of free electrons in this copper material per unit volume. Thus, the drift speed of the electrons is V = ngA c) x 1028 m-1.60 x 10-19 C)(T x 10-4 m2) x 10 m/s.
An experimental device uses electrical energy to accelerate a projectile motion. Using dimensional analysis alone, what can you determine about how the accelerating force, F, depends on the current, I, if the only other quantities which need to be considered are the thickness of the rails, d, the distance between the rails,D, and the constant known as the permeability of free space, µo. 2 The value of uo is 47 × 10-7 N/A², so [µo] = .

You are working in a factory that produces long bars of copper with a square cross section. In one section of the production process, the bars must slide down a plane inclined at an angle 8 = 24.0° to the horizontal. It has been found that the bars travel with too high a speed and become dented or bent when they arrive at the bottom of the plane and must be discarded. In order to prevent this waste, you devise a way to deliver the bars at the bottom of the plane at a lower speed. You replace the inclined plane with a pair of parallel metal rails, shown in the fiqure below, separated by a distance { = 2.10 m. R m The smooth bars of mass m = 1.00 kg will slide down the smooth rails, with the length of the bar always perpendicular to the rails. The rails are immersed in a magnetic field of magnitude B, and a resistor of resistance R = 1.25 N is connected between the upper ends of the rails. Determine the magnetic field necessary (in T) in your device so that the bars will arrive at the…
The figure below shows a long conducting coaxial cable and gives its radii (R₁ = 3.9cm, R₂-8.6cm, R3-17.1cm). The inner cable has a uniform current density of J = 7.2 A/m², and the outer cable carries a uniform current | = 4.3A flowing in opposite direction. Assume that the currents in each wire is uniformly distributed over its cross section. Determine the magnitude of the magnetic field in terms of μ at a distance r = 23.1cm from the center of the cable. Express your answer using two decimal places. R₂ R3 I
