Achild (approximately 4 years old) takes her metal “slinky toy” (a flexible coiled metal spring) and does various tests to determine that the slinky has an inductance 130 µh, when it has been stretched to a length of 3 m. the permeability of free space is 4π × 10−7 n/a 2 . if a slinky has a radius of 4 cm, what is the total number of turns in the slinky?
