Question

You need to bend the path of a beam of electrons by 90° for an experiment, so you make a loop of 2. current with N turns and a radius of 15 cm to do it. In order for the electrons to turn by 90°, they have to follow a circular path with the same radius as the loop of wire. 0 (10 points) If the electrons are traveling at 5% the speed of light, how strong does the magnetic field have to be to turn the electrons by 90°? (10 points) If you make the loop out of magnet wire, then the loop can carry a maximum current of 1.4 A. Approximately how many loops would you need to to produce the magnetic field in part a? (10 points) Magnet wire has a diameter of 0.321 mm. wire it would produce a magnetic field of 54.8 Gs. How many turns in a loop of wire would be needed to produce this field? Is this number feasible? a. b. 9 c. If you made a solenoid from magnet 3. (10 points) The Milky Way Galaxy has its own magnetic field. In the region near the sun (and earth) this magnetic field has has a value of about 6 uGs. Cosmic rays consist mostly of light particles, but some heavier particles can be found in cosmic rays, even some as heavy as lead. These particles are stripped of all of their electrons, giving the particles of lead a charge of +82e, and a mass of about 208 times the mass of a proton Ifone of these particles moves at 10% the speed of light perpendicular to the magnetic field, what is the radius of the circular path it moves along?
