- uppose you are working on a science lab in which your professor asks you to turn a knob 750 on the detector you are using. Unfortunately, you have been working in radians for a while, so you are having trouble remembering how far to turn the knob. How would you translate the instructions in degrees to radians?Discuss the effect of changing field size on PDD. Explain why this effect occurs.(L10) A 5.54E-2 m by 3.67E-2 m rectangular loop of wire carries a current of 1.62 A. What is the magnetic moment of the loop (in A-m²)?
- 29. A hydrogen isotope separator contains positively ionized hydrogen H', with isotope of hydrogen, Deuterium D<, and other heavy particles, and the ions were released in a potential difference of 200 Volts. The strong magnetic field of 1.4x10 Tesla (out of the page), bends the ions and Deuterium is collected on separate ionic trap as shown in the figure. (Masses MH1=1.67x10°2/ kg, Mp2=2* MH1, Q(H1, D2) = 1.6x10~19 C) What are the velocities of the Deuterium when exiting the plates, in unit of 105 m/s?Chapter 29: Magnetic Fields We studied how a moving charge would react in a magnetic field, which extends naturally to current where charges drift (hence moves) in a magnetic field. One special case of this is the torque due to current loops in magnetic fields: 7= μx B= IAX B since we defined the magnetic moment of a current loop as μ = IĀ. estimate the current that an electric car would have to provide to its motor such that it can do 0-100 kph in 3 seconds. Some useful hints for guidance are below: (1) . Find the acceleration using kinematics With the acceleration, what would be the torque needed for the motor to apply to the wheel? You need to estimate yourself the size of the wheel, as well as the size of the motor hub that is connected to the wheel. A simple electric motor has a permanent magnet, say of strength of 1 Tesla, and a coil acting as many current loops. You need to estimate the number of loops, you can google it just come up with a reasonable number. ● From this and…An electron is placed in a magnetic field B that is directed along a z axis.
