Two parallel wires whose centers are 24.00 cm apart carry equal currents in opposite directions. Find the inductance of a 140.00 cm length of such a pair of wires. The radius of each of the wires is 0.05 cm.
Two identical long wires of radius a = 1.60 mm are parallel and carry identical currents in opposite directions. Their center-to-center separation is d = 11.3 cm. Neglect the flux within the wires but consider the flux in the region between the wires. What is the inductance per unit length of the wires?
Two long coaxial solenoids each carry current I but in opposite directions as shown in the figure. The inner solenoid of radius R1 has n1 turns per unit length, and the outer solenoid with radius R2 has n2 turns per unit length. What is the expression for the magnitude of the magnetic field inside the inner solenoid?
