Your teams investigating the possibility of making electrically controlled values that open and close the input and exhaust openings for an internal combustion engine. You assignment is to determine the stability of the valve by casting the foreh of its sides and the net force on the valve. The values made of a thin bu rectangular piece of non magnetic material that has a foop of current carrying we along its edges. The rectangle is 0.35 cm 1.83 cm. The value is placed in a uniform magnetic field of 0 15 Tsuch that the field lies in the plane of the vale and is per to the short sides of the rectangle. The region with the magnetic fields Larger than the valve. When a switch is closed a 17 A current enters the short side of the rectangle on one side of the valve and leaves on the opposite side. Top different currents through the wires along the long sides of the valve are inserted into the wire on each oft. 2. You have landed a great summer job in the medical school nating in a research group investigating short lived radioactive hotopes which might be useful info cancer. Your group is working on a way of transporting alpha partides them nuclei) from where they are made to another room where they will collide other material to form the isotopes. Since the radioactive isotopes are not to live very long. It is important to know precisely how much time it will transport the alpha particles. Your job is to design that part of the transport system which will deflect the beam of alpha particles in 55€ 30-270-3230330 through an angle of 900 by using a magnetic field. The beam will be trawing horizontally in an evacuated tube. At the place the tube to make a turn you decide to put a dipole magnet which provides a uniform vertical magnetic field of 0.030. Your design has a tube of the appropriate shape between the poles of the magnetBefore you submit your design for consideration, you must determine how long the alpha particles will spend in the uniform magnetic field in order to make the 9 turn 3-You've just learned about the earth's magnetic field and how a compens works and you are relaxing in front of the TV. Tired of your show you think about how the picture tube works in relation to what you have banned in a typical color picture tube for a TV, the electrons are boiled off of a cathode at the back of the tube and are accelerated through about 20,000 volts towards the picture tube screen on the screen in a grid of color des" about 1/100 inch apart. When the electrons the the dots scintillate their appropriate colors producing the color picture without taking apart the set you determine whether the manufacturer needed to see color picture tube from the earth's magnetic field?
