The figure below shows a portion of a silver ribbon with z1 = 11.8 mm and y1 = 0.23 mm, carrying a current of 102 A in the +x-direction. The ribbon lies in a uniform magnetic field, in the y-direction, with magnitude 1.09 T. Apply the simplified model of the Hall effect presented in Section 27.9. They are 5.85 1028 free electron per cubic meter. The figure below shows a portion of a silver ribbon with z1 11.8 mm and...
The figure (Figure 1) shows a portion of a silver ribbon with z1 = 12.0mm and y1 = 0.23mm , carrying a current of 110A in the +x-direction. The ribbon lies in a uniform magnetic field, in the y-direction, with magnitude 0.91T . Apply the simplified model of the Hall effect. Part A If there are 5.75?1028 free electrons per cubic meter, find the magnitude of the drift velocity of the electrons in the x-direction. Part B Find the magnitude...
The figure shows a portion of a silver ribbon with z_1 = 14.0 mm and y_1 = 0.21 mm, carrying a current of 120 A in the + x-direction. The ribbon lies in a uniform magnetic field, in the y-direction, with magnitude 0.90 T. Apply the simplified model of the Hall effect.
The figure below shows a cross-section of two long, straight, parallel wires, where the currents are flowing perpendicular to the page. Wire 1 carries a current I1 directed into the page (in the −z direction) and passes through the x-axis at x = +a. Wire 2 passes through the x-axis at x = −2a and carries an unknown current I2. The total magnetic field at the origin due to the current-carrying wires has the magnitude 2μ0I1 (2πa) . Note that...

QUESTION 5 Consider a portion of a current-carrying wire as shown in the figure at right with the current direction as indicated. In determining the magnetic field at point P what will be the direction of † ? Р into the page in the same direction as the current out of the page towards point P to the left
1. The figure on the left shows the current, 1, of a long straight wire coming out of the page. The figure on the right shows the direction of the magnetic field as it passes through the plane of the page for a vertical current-carrying wire (center) For the figure on the left draw the magnetic field of the wire; for the figure on the right indicate the direction of the current. O O Bout I (out)
