A long, straight wire of radius a = 2.0 cm is located along the z-axis and carries a current I1 = 2.1 A in the negative 2-direction. A cylindrical conducting shell of inner radius b= 4.0 cm and outer radius c = 5.7 cm coaxial with the wire carries a uniformly distributed current 12 = 7.1 A in the positive z-direction as shown. Figure 1: (a) What are the r- and y-components of the magnetic field at point A located...
A solenoid is wound with 370 turns on a form 4.0 cm in diameter and 50 cm long. The windings carry a current I in the sense that is shown in the figure. The current produces a magnetic field, of magnitude 4.9 mT, near the center of the solenoid. Find the current in the solenoid windings. (μ 0 = 4π × 10-7 T · m/A)
(Figure 1) shows five electric charges Four charges with the magnitude of the charge 2.0 nC form a square with the size a = 4.0 cm. Positive charge with the magnitude of q = 4.0 nC is placed in the center of the square. Part AWhat is the magnitude of the force on the 4.0 nC charge in the middle of the figure due to the four other charges? Part B What is the direction of the force on the 4.0 nC charge...
