- The accompanying figure shows two long, straight, horizontal wires that are parallel and a distance 2a apart. If both wires carry current I in the same direction, (a) What is the magnetic field at P1 in terms of μ0, 'I', and 'a'? (b) What is the magnetic field at P2 in terms of μ0, 'I', and 'a'?A small particle with negative charge q = -12 x 10-3 is traveling between two large parallel plates that have charges of equal magnitude and opposite sign. The speed of the particle is 550 m/s. There is a uniform magnetic field in between the plates with magnitude of 5.0 T and its direction is out of the page. What are the magnitude and direction of the uniform electric field between the plates if the particle travels in between the plates without being deflected?Ho Idlxf 4π 72 dB This problem checks your understanding of the term in the equation for the magnetic field due to a small "piece" of current, Consider a small piece of current (perhaps there's a wire) at location $ whose coordinates are (6 m, 2 m, 10 m). We would like to find the magnetic field at location P whose coordinates are (2 m, 5 m, 2 m). The term " is the distance between point S and point P. What is its value, in meters?
- •P А. В. d D ° Now we're viewing a cross-section of a solenoid that has n turns per unit length and a current I. The solenoid is very long – we can consider it to be infinitely long for our purposes – and the individual colds are very tightly packed. a. What's the direction of the magnetic field inside the solenoid? (Hint: use your knowledge of the field produced by currents to vector-add the fields at each point.) You can write your answer here or upload a picture of your drawn arrows. b. How does the magnitude of the magnetic field vary from point A to point B? What about from point C to point D? The magnetic field outside the solenoid (e.g. at point P) is zero. Explain why this makes sense. Draw an Amperian loop that includes points A and P. What shape of a loop makes sense to use, for the purpose of finding the magnetic field at point A? Explain why you chose the shape you chose. d. Use Ampere's law to find the magnitude of the magnetic field at point A inside the solenoid.

Compute the magnetic field strength that this motion produces at the location of the proton. Answer in units of T.1.70 x 104 - m In 1996, NASA performed an experiment called the Tethered Satellite experiment. In this experiment, a length of wire was let out by the space shuttle Atlantis to generate a motional emf. The shuttle had an orbital speed of 7.70 x 10³ m/s, and the magnitude of the earth's magnetic field at the location of the wire was 5.10 x 10-5 T. If the wire had moved perpendicular to the earth's magnetic field, wat would have been the motional emf generated between the ends of the wire? Gr C

Ions in the beam emerge from the velocity selector at a speed of 2.78 x 105 m/s and enter a uniform magnetic field of 0.575 T directed perpendicularly to the velocity of the ions. What is the distance between the impact points formed on the photographic plate by singly charged ions of 235U and 238U? cm Need Help? Read ItAn electron moves with a velocity of 5.2 X 106 m / s, as shown in the image. Calculate the magnitude and direction of the generated magnetic field by the motion of the electron at points A, B, C, and D, where the distance a said is points is 7 nmIf the currents in these wires have the same magnitude and directions,what is the direction of the magnetic field at point P?
