the figure below shows a long Previous Answers OSUniPhys1 29.3.WA.021 My Notes Ask Your Teacher 4. 1/2 points | The figure below shows a long straight wire near a rectangular current loop. The current in the wire is 11-12.0A and the current in the loop is 12-30.0A The dimensions of the loop are L 36.0 cmw 12.0 cm, and the distance from the loop to the wire is r -7.50 cm. Determine the magnitude and direction of the total force on the loop magnitude What physical quantities determine the magnetic force produced by two straight, parallel, current-carrying wires? N direction away from the wire 2-300A Additional Materials eBook Submit Answer Save Progress Practice Another VersionExplanation / Answer
a) F = [mu0 I1 I2 l / 2pi r] - [mu0 I1 I2 l / 2pi (r+w)]
F = [mu0 I1 I2 l / 2pi ] * [1/r - 1/r+w]
= [4 pi * 10-7 * 12 * 30 * 0.36 / 2 pi] [1/0.075 - 1/(0.075+0.12)]
= 2.592 * 10-5 * 8.205
magnitude = 2.13 * 10-4 N
b) away from the wire
