A cyclotron with a 0.5 T magnetic field is fed a stream of electrons traveling at 500,000 m/s. Find the radius of their circular orbit and their circulating frequency.
QUESTION 6 The allowed safe current for a No. 3 copper wire, 0.2294 inch in diameter, is 100 A. How many coulombs of charge pass a cross-section of the wire in 0.5 minutes? Assume the electron concentration in copper wire is about 2 x 102④ electrons/in3, the average electron velocity is about 2.5 inches/s, and the charge per electron is 1.6x 1019 C. (Enter your answer as a number with the coulombs units.)

A long straight wire sits on the z-axis and carries a current of 2.92 amps in the positive z direction. A uniform external magnetic field of 8.08 T points in a direction that makes an angle of 39.5 degrees with the wire. Find the magnitude of the force on the section of wire that runs from z = 0 m to z = 6.79 m. Answer in units of N.
Question 2 1 pts Calculate the magnetic field of a current-carrying wire (1-5 A) at a distance of 7 meters. Give your answer in Microtesla and use two decimal places.
A wire carrying a current of 0.25 A is 0.5 m long. a) If the wire has a mass of 5 g, how much is the gravitational force on the wire? b) If the wire is directed from east to west with an upward force, will it accelerate upward in the magnetic field, fall to the ground, or just hover motionless? Explain why
5. Using a surface integral calculation, find the current (in Amps) in a circular wire given a current density of)s 15(1-e-1000r)ez Amps/㎡ . That is, J has a magnitude of 15(1-e-1000r)as it is a function of distance r from the center to the outer surface. J points in the z direction. Draw the wire in a diagram with the cylindrical coordinate system and solve for I using a double integral. Hint- what is the surface area of the end of...
