For the current carrying wire shown in the figure below, I = 25.1 A, r1 = 5 cm, and r2 = 10 cm. The direction of the current is indicated in the figure. Find the magnitude and direction of the magnetic field at point P. Note, the top vertical wire and the right horizontal wire are semi-infınite wires. For direction, use positive for into the page and negative for out of the page. I r2

For any vector quantity, be sure to always include the magnitude and direction ty

Two very long parallel conductors are located at a distance of 2 a from each other, perpendicular to the plane of the figure below. The left-side conductor is carrying a current of i= 4 A directed into the page. What current i, (magnitude and direction) must flow through right-side conductor to produce a zero magnetic field at point P₂? Use out of the page as the positive direction and a = 3 cm and b = 14 cm. y i The current, ix a P₁ 1 The magnitude of the B-field, B₁ = The field is directed Down Submit Question 14 a Units A What is the magnitude and direction of the magnetic field at point P₁?

A conductive wire is arranged on the surface of the cube whose sides are 40 cm as shown. The wire is in the same magnetic field B = 0.02 T j. If the conductor is energized by an electric current I = 4 A in the direction shown in the picture, determine the vector of the magnetic force experienced by each piece of wire.
