An infinitely long wire carries a current of I1=6.0 A along the x-axis and another infinitely long wire carries a I2=8.0 A current along the y-axis as shown in the figure. What is the magnitude of the resulting magnetic field at the point P, located at x = 2.0 m and y = 4.0 m? In your work, explain the direction of the magnetic field at P.

In the arrangement shown, a conducting bar of negligible resistance slides along horizontal, parallel, frictionless conducting rails connected as shown to a 10-Ω resistor. A uniform 3.3-T magnetic field is perpendicular, into the plane of the page. If L = 50 cm, what is the magnitude and direction of the current generated in the loop at the instant the bar is moving to the left at 7.3 m/s? In your work, and in your own words, explain why the current flows in the direction you selected.

The bar magnet is above the conducting loop, but falling toward it. The resistor R is located on the side of the loop closest to you. As the magnet approaches the loop, choose the correct statement below. Then explain, in your own words, why the current flows in the direction you selected. Do not use the phrases “Lenz’s law” or “Faraday’s law.”
