-piz h d The figure shows the cross section through three long wires with a linear mass distribution of 117 9/m. They carry currents /1, i2, and is in the directions shown. Wires 2 and 3 are 11.9 cm apart and are attached to a vertical surface, and each carries a current of 687 A. What current, i, will allow wire 1 to "float" at a perpendicular distance d = 13.3 cm from the vertical surface? (Neglect the thickness of the wires.) Submit Answer Tries 0/100A current of 1.85 A is flowing through a 2785 turn solenoid of length & = 35.1 cm. What is the magnitude of the magnetic field inside the solenoid? Submit Answer Incorrect.

The radius of the coil is R = 4.99 cm, and the angle between the magnetic field vector and the unit normal B vector to the coil is 0 = 60.09. The current through the N S coil is / = 6.73 A. a) Calculate the number of turns, n, the coil must have for the torque on the loop to be 3.83 N m.
