A conducting bar of length I and mass m rests at the left end of the two frictionless rails of length d in thefigure below. A uniform magnetic field of strength B points upward.a) In which direction, into or out of the page, will a current through the conducting bar cause the barto experience a force to the right?b)Assuming a current I in the direction you found in part (a), find an expression for the bar's speedas it leaves the rails at the right end.

A loop of wire is perpendicular to a magnetic field. The magnetic field strength as a function of timeis given by the top graph. Draw a graph of the current in the loop as a function of time. Let apositive current represent a current that comes out of the top of the loop and enters the bottom of theloop. There are no numbers for the vertical axis, but your graph should have the correct shape andproportions.
You are working during the summer at a company that bulds theme parks. The company is designing an electromagnetic propulsion system for a new roller coaster. A model of a substructure of the device appears in the figure below. The rod is of length d- 1.00 m and mass m-0.400 kg. The rod carries a current i- 100 A in the direction shown and rols along the rails of length i- 20.0 m without slipping. The entire system of rod and rails is immersed in a uniform downward-directed magnetic field with magnitude 2.10 T. The electromagnetic force on the rod is parallel to the rals, causing the rod to roll to the right in the figure. Wwhen a full scale device is produced, this rod wil represent the axle of wheels on which the car and its passengers ride. The electromagnetic force on the axde will provide the motion of the car at the beginning of the roller-coaster ride. Your supervisor wants to test the substructure in the figure in a flat outdoor area on the grounds of the company. By projecting…
A long, cylindrical conductor of radius R carries a current I as shown in the figure below. The current density J, however, is not uniform over the cross-section of the conductor but is a function of the radius according to J = 2br, where b is a constant? Find an expression for the magnetic field magnitude B at the following distances, measured from the axis. (Use the following variables as necessary: ?0, r1, r2, b, R.) (a) r1 < R (b) r2 > R
Let x=0 be the beginning of the magnetic field. Express the area (A), and express vw in terms of the area. Then what is vBw in terms of magnetic flux? The magnetic force on the conducting charges is an EMF, an electromotive force. Use these to derive the following expression for the EMF: Please see attachments for details on question and diagram.
A current I is passed through a wire. A second wire of length L is moving perpendicular to the magnetic field generated by the first wire (see sketch below) with velocity v at a distance d. Write down the expression for the potential difference V between the ends of the moving wire. Consider the magnetic field B to be constant over the range of motion of the second wire (i.e. d » 1). Use μ for the vacuum permittivity. Please use appropriate algebraic symbols for multiplication (* for a × b), division (/ for a/b), exponents (a^b for a³), square root (sqrt(a*b/c) for √a× b/c) etc. For Greek letters use their names e.g. "theta", "alpha", "pi", "mu" (without the quotes) and for trigonometric functions use "cos", "tan", "sin" (without the quotes). Thus for Acose use A*cos theta. Please use the "Display response" button to check you entered the answer you expect. Wire 1 Wire 2 d V
