Macmillan Learning Tarik winds a small paper tube uniformly with 157 turns of thin wire to form a solenoid. The tube's diameter is 7.01 mm and its length is 2.07 cm. What is the inductance, in microhenrys, of Tarik's solenoid? inductance: H

A long solenoid is created with 33 turns, has a radius of 1.6 mm, and a length of 1.93 cm.-What is the inductance L of the solenoid?

4. The graph shows the current through the ideal inductor as a function of time after the switch is thrown to (a). Determine the time constant of the circuit. Comment: the way to do this is to note that when t = T₁, the current is 1 Io (1e-¹) = 0.63 1. a. b. The inductance is 1.2 H. What is the resistance r? Current (mA) 2 1.5 1 0.5 2 4 8 10 12 14 6 time (ms) c. What is the EMF E? Hint: use the fact that the inductor will act like a wire at very long times. d. What is the voltage across the inductor at t = 6 ms? Hint: use the results from (b) and (c) and the loop rule.

A thin coil has 12 rectangular turns of wire. When a current of 1.7 A runs through the coil, there is a total flux of 0.005 T-m² enclosed by one turn of the coil (note that the inductance is the proportionality constant between current and magnetic flux). What is the total inductance in Henries? H
