PHYS-102 Homework-08 Solutions Chapter-22 Magnetic Forces and Fields P22.27 We can think of the total magnetic field as the superposition of the field due to the long straight wire (having magnitude μ 0 I 2 π R and directed into the page) and the field due to the circular loop (having magnitude μ 0 I 2 R and directed into the page). The resultant magnetic field is: G B = 1 + 1 π μ 0 I 2 R directed into the page ( ) . P22.38 Let the current I be to the right. It creates a field B = μ 0 I 2 π d at the proton’s location. And we have a balance between the weight of the proton and the magnetic force

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
