* Question
| Inductor application |
* Answer
| Assume that the coil is 2 meters in diameter and contains five or six wire loops.You engrave the groove on a road and place the coil in the groove.Place the inductance meter on the coil and see what the inductance of the coil is.Then you can park a car on the coil and measure the inductance again.When the inductance rises, it knows that there is a car waiting!Usually the coil you use is much smaller than this.An important use of inductors is to work with capacitors to build an oscillator. |
