# # 💡 Important Tips for Languages Students:

* اعمل **Glossary**:
*(law – definition – symbol – unit)*
* الحل يكون **step by step + clear English**
* احفظ **definitions word by word**
* الرسومات مهمّة جدًا ✍️

1- In emf=-Blv
Length is displacement not distance
2-if B=10 then B=2
So B is decreased

3-opened f=o
Closed f=Bil
4- i=emf-vB/R

5-v=d/t
AB and cD
Emf =o bec parallel to velocity

1-The parallel series must be reviewed during self-induction.

2-EMF forward, which occurs during opening, is much larger than EMF backward, which occurs during closing.

3- Self induction and mutual induction
Can be called inertia of electricity

4- At the moment of closing i=0

5-Backward is small, but its value is not zero.

6-Delta i /delta t
Is called rate ofcurrent growing

7-The units of self-induction are determined from Manal's law, Faraday's law, and the relationship between Henry's EMF law and Faraday's EMF law.

8-M=root L1 L2

9-Backward Hinders the growth of i

10-Double folding
Emf =zero L=o

11-Self induction of straight wire =zero

12-Self induction direct with time

13-Emf = - slope
