Use the Biot-Savart law to derive an expression for the magnetic field a distance wire carrying current l Hints: from an infinitely long lds dx P ● The Biot-Savart Law says B-40 .Only calculate the magnitude of the field. It's fine to 4π calculate B = goff las,1, we defined the direction in class using the right hand rule Consider the diagram: ld × fl = ld llfl sin θ. Since f is a unit vector, Ifl = 1, so...
Use Biot-Savart Law to find the magnetic flux density at a point P which is 2 meters away from a one a wire one meter long carrying 5 A. The orientation of the wire is at right angles to the line connecting the center of the wire and point P.
7. Using the Biot-Savart-Law, determine the magnetic field at point C due the current loop seen in the figure below, where the two arcs are segments of two circles with radii Ri and R2 respectively, and with their centers located at C. The current, I, circulates through the loop in counter-clockwise direction. Your expression should depend only on the two radii, the current and the angle θ
3. (a) Use Biot-Savart Law to find the magnetic field of wire, along the z-axis, carrying a current I (in direction), at a point P a distance r from the wire. Do this for both a finite wire (21 <2<z2), and an infinite wire (-0<z< too). (6) Use the result of part (a) to evaluate the net magnetic field of the wires shown at point P (0,0,2).
