| 7 | When the movement of the road to the left perpendicularly on uniform magnetic flux, the magnetic force (FB) Affects in the positive charge and its direction will be upward toward (a) (According to the right hand rule), then, the positive charges gather on (a) end, and the negative charges gather on the (b) end, consequently an electric field (E) is created which directed down wand (from a to b), when the direction of the movement of the rod is reversed (towards the right), the direction of magnetic force reverses, therefore, the positive charges gather on the (b) end and the negative charges gather on the (a) end, so the direction of an electric field (E) will be from (b) to (a). | 410 |

| 10 | If the conducting rod (ab) shown in the figure moves horizontally to the left in the plane of the page inside a uniform magnetic field directed perpendicularly out of the page (towards the viewer), an electric field is generated inside the rod directed towards end (b). However, if this rod moves to the right inside the same magnetic field, the direction of the electric field inside it reverses towards end (a). What is the explanation for this? | 495 |

| 12 | سؤال وزاري ‼️ | 484 |
| 13 | مساء الخير 🤍 | 498 |
| 14 | 🔸 how did the electric circuit dissipates the power ?
🔹 the electric circuit dissipates the power in the form of thermal power in the total resistance (R) in the circuit (items of the circuit and connecting wires), | 648 |
| 15 | 🔹 كيف تتسبب الدائرة الكهربائية في تبدد القدرة ؟
🔸 نجد أن الدائرة الكهربائية تتسيب في تبدد القدرة بشكل قدرة حرارية تظهر في المقاومة الكلية R في الدائرة (عناصر الدائرة واسلاك الربط)، | 638 |
| 16 | 🔸 what is power ?
🔹 is defined as time rate of work done | 626 |
| 17 | 🔹 ماهي القدرة ؟
🔸 تعرف بأنها المعدل الزمني للشغل المنجز | 608 |
| 18 | 🔸 power relation and power dissipated relation are equal. What dose that means?
🔹 The time rate of work done in moving the conductor rod through a magnetic field equals exactly the dissipated power in the total resistance of this circuit as a heat or any kind of power in load. This is an application of conservation law of energy. | 601 |
| 19 | 🔹 علاقة القدرة وعلاقة القدرة المتبددة متساويتان. ماذا يعني ذلك ؟
🔸 يعني ان المعدل الزمني للشغل المنجز في تحريك الساق الموصلة خلال المجال المغناطيسي يساوي بالضبط القدرة المتبددة في المقاومة الكلية لهذه الدائرة بشكل حرارة او اي نوع من القدرة في الحمل وهذا يعد تطبيقا لقانون حفظ الطاقة. | 522 |
