I only need help with questions 4,5,6,7, and 8. thanks Magnetic field and Magnetic Force due to a (long, straight) current PHYS 181 - in class problem set An infinitely long conductor carrying current is bent at a right angle as shown in Figure 1. Point P is located a distance b from the corner of the wire. Only one section of this current contributes to the magnetic field at pt. P. Why? The general formula (derived from the Biot-Savart...
Please show work and explanation. thanks Physics 51 Practice Final Problem #1 : Two electrons are at opposite corners of a 10cm-per-side square, as shown. A long wire carrying 200mA runs through another corner of the square. The bottom electron is moving towards the top electron at lkm/s electron 10cmV-lkm/s I-200mA nto page electron 10cm A) Find the magnitude and direction of the electric and magnetic fields at the location of the moving electron (the bottom one). Make sure your...

2. Consider a system with two electrical line currents in the +z direction, 11-1 and 12-21 located at Fi and F2, respectively, with all coordinates defined as in the previous problem. (a) Sketch the field lines corresponding to the total magnetic field in the xy plane due to the two line currents. (b) If the vectors FiP and hP that point from the line currents to the field point are different than in the previous problem, determine them and their...
Please show all work (every bit) and all units. Also please wrote clearly. I need soon. Thanks. 4. (30 pts) a) (10 pts) A 12 turn coil encloses an elliptical area having a major axis of 50 cm and a minor axis of 30 cm. The coil lies in the plane of the page. The wire making up the coil carries a current of 6 A in a clockwise direction. If the coil is in a uniform magnetic field of...
ke=8.99XIU' N.1 Problem 4 A copper wire has a circular cross section with a diameter of 1.25 mm. (i) If the wire carries a current of 2A, find the drift speed of electrons in this wire. (ii) All other things being equal, what happens to the drift speed if the wire is made of a different metal, having a larger number of conduction electrons than copper? M=0.063 kg/mol; p=8.9 g/cm3. Problem 5 A proton moves perpendicular to a uniform magnetic...
