| If a conductor moves through a magnetic field, a voltage is generated on the conductor. This effect is called __________. In order for this to occur, you must have a magnetic field and a moving conductor. | electromagnetic induction |
| Electromagnetic induction can also be seen when 2 conductors are put near each other in parallel. When the current in one of the conductors is varied (w/ conductor not moving), a voltage is induced in the other conductor. This type of elect.mag. induction is called ______ induction. | mutual |
| The strength of the voltage induced in a conductor that's moving in a mag. field depends on these factors: ____ of the field the conductor's moving through, ____ that it's moving, ____ & ____ of conductor's coil, and the ____ the conductor makes with the mag. field. | strength, speed, length & number, angle |
| If a current-carrying conductor (ccc) is placed in a mag. field, the interaction between the field and the moving electrons in the ccc causes a force to be applied to the ccc. If the ccc is free to move, the force will move the ccc as long as its current and the mag. field are maintained. This process is called the _______________________. | motor action of electromagnetic induction |
| __________ - Pretend that you're doing a hand gun. Point your pointer finger in the direction of the mag. lines of force. Then point your middle finger in the direction of current flow. Your thumb now points in the direction that the conductor will move. This is used to identify w/ way the conductor will move / motor action of elect.mag. inductoion. | Flemming's Left-Hand Rule |
| Flemming's Left-Hand Rule is also called the _____ rule. | motor |
| If 2 conductors are formed into coils and placed near each other and current is applied to the 1st coil, the mag. field made by the 1st coil induces voltage in the 2nd coil. In this arrangement, the 1st coil is called the _____ coil, and the 2nd id called the ______ coil. | primary, secondary |
| A _____ consists of two parallel coils wound around an iron core. | transformer |
| Coils are also called _____. | windings |
