A solenoid of radius 2.30 cm has 560 turns and a length of 25.0 cm. (a) Find its inductance. 18.4 x Apply the expression for the inductance of a solenoid. mH (b) Find the rate at which current must change through it to produce an emf of 50.0 mV. (Enter the magnitude.) 2.71 X You appear to have used the value of the inductance you found in part (a) of the problem to calculate the rate of change of the current, but because your answer to part (a) was incorrect, your answer to this part is also incorrect.
