In which direction must current flow in the looop to produce zero magnetic field at its center? Show magentic vectors pleaseA velocity selector uses a 1.0T magnetic eld to select protons traveling at 2:0 106m=s. Pleaseindicate how strong E needs to be. Also draw a picture of both E and B (with orientations indicated)that will work for a proton which enters the right side of the velocity selector and exits the left.Cont.
- Consider a charged particle moving through a region in which the electric field is perpendicular to the magnetic field, with both fields perpendicular to the initial velocity of the particle (see figure below). Such a device is called a velocity selector because for one particular value of the particle speed select the particle will travel straight through the device without being deflected, whereas particles with speeds that are either less than or greater than Vselect will be deflected. Consider a case with E = 505 V/m and B = 0.11 T. B Perspective view AE = 'select v>F'select (a) When protons are used, what speed is selected? m/s (b) What is the speed selected for Ca²+ ions? m/s (c) If you were to use your selector with Fions, what change would be necessary?Five particles follow the paths shown in the figure as they pass through a magnetic field. The direction of the field is indicated by either dots or crosses in the figure. What can you conclude about the charge of each particle?A charged particle moves in a magnetic field with a velocity of 300 m/s at an angle of 60 degrees to the magnetic field lines. If the charge on the particle is 1.5 μC and the magnetic field strength is 0.4 T, calculate the magnetic force acting on the particle.
- A particle moves through an electric field as shown in the figure. What is the direction of the magnetic field needed to ensure that the particle experiences zero net force?What is the magnetic field at the origin? There are five straight segnments and a half circle as seen in the image below. Specify the diretion relative to the page.A velocity selector is a device that can choose the velocity of a charged particle moving through a region in which the electric field is perpendicular to the magnetic field, and both fields perpendicular to the initial velocity of the particle as shown in the figure. To make the charged particle travel straight through the parallel plates, the downward deflection due to electric field must equal the upward deflection due to the magnetic field. Suppose you want to design a velocity selector that will allow protons to pass through, undeflected, only if they have a speed of 500 m/s. The magnetic field is B=0.05 T. Calculate the electric field you need. a 90 V/m b 75 V/m c 25 V/m d 50 V/m
