different orientations of this idealized square coil are shown in the drawing below. The top two pictures are identical to the bottom two pictures. Draw arrows representing the magnetie forces on the sides of the coil. в в в в Indicate the sides of the coll where the magnetic force would cause the coil to rotate. B в в Use these pictorial representations to perform the following analysis: 1) On the top two pictures draw the direction of the magnetic force on each side of the square and on the wires entering and exiting the loop. 2) On the bottom pictures indicate which forces would cause the loop to rotate.

Find the direction of the magnetic field at each of the indicated points. What is the direction of the magnetic field Bc at Point C? O Bc is out of the page. O Bc is into the page. O Bc is neither out of nor into the page and Bc + 0. O Bc = 0. Figure 1 of 2 Part D What is the direction of the magnetic field Bp at Point D? A O Bp is out of the page. O Bp is into the page. O Bp is neither out of nor into the page and BD # 0. O BD = 0

I need help on question 8?

Following conventional current flow, what would be the direction of the induced magnetic field and the direction of the current for the two situations, a) right after the switch is closed b) the switch has been closed for a long time and now right after the switch has been opened? See figure below. The figure on the left is a battery connected to a coil. The figure on the right is a coil connected to an amp meter. Determine which direction the amp meter shows current for each situation.

A long, straight wire carries a current I (see figure below). Which of the following statements is true regarding the magnetic field due to the wire? More than one statement may be correct The magnitude is proportional to I/r, and the direction is out of the page at P. The magnitude is proportional to I/r2, and the direction is into the page at P. The magnitude is proportional to I/r, and the direction is into the page at P. The magnitude is proportional to I, but does not depend on r. The magnitude is proportional to I/r2, and the direction is out of the page at P..

a L I b L Two long, thin, parallel wires are suspended via 7 cm strings as shown in the Figure above. Each wire has a linear mass density of 55 g/cm. The wires carry identical currents in opposite directions, as shown. a. Use (make a copy) panel b of the Figure above to draw a Free Body Diagram showing the forces acting on one of the wires. b. Find the current in the wires if the system is in equilibrium when the suspending strings make a 6.5 degree angle with respect to the vertical.

Please solve the question correctly and also be sure to give the correct units. Thank you!
