Q6. The formula for the inductance of a long solenoid is L= 4N°4 H =1.26 x 10-6Tm/ N = number of loops A = cross, sectional area 1= length Calculate the coil's inductance. The coil has 22,478 loops, a diameter of 10.0 cm and a length of 10.0 cm. Show your work. L = (what are the units of L?) Note: For the purpose of this computer laboratory the value for L you just calculated is artificially high so you were able to visualize the current and time it (in -6 -3 Q8). Typical values of inductance range, 100 - 10³.
