Sorry for not updating a new post for quite sometime. I have lots of work need to be looked after. The truth is i'm also learning how to mange my time properly.
As a muslim we've been thaught to pray 5 times a day at different times. It shows that islam teaches us to manage our time properly.Thats why Rasullulah(saw) in one of HIS hadith asked us to appreciate our free time b4 its getting busy.
As i told u b4, time management in study is so crucial. You are now have a lesser time..so please use it wisely.
Anyway lets continue with our discussion on electromagetism..
We've discussed Lenz's law b4. The next will be Faraday's law.
We should thank this guy for his amazing discovery which then allow us to ride a bicycle at nite with dynamo.
In SPM u must be able to state each Laws that u learn..
so far in F5 we've learned Ohm's Law & Lenz's law. Usually question will ask u to state this law & 1 mark is given.
Some of my stdnt said, "its 1 mark only sir"..so they dont bother to memorize them..
Well my advice is ..who knows,may be that 1 mark is the one that separate u frm getting an 'A'..
So..are u willing to loose it???
Ok..lets go straight to the point..
What is Faraday's law??
Faraday's law states that:
magnitude of the induced current is directly proportional to the rate of cutting of magnetic flux.
This law is much easier to undrtand then Lenz's law. Its quite straight foward..
If u cut more magnetic field, u'll get more induce current. Thats why, if u ride a bicycle with dynamo at nite, the faster u cycle, the brighter the bulb. In dynamo itself theres a process of cutting of mgnetic fields which generate induce current that lights up the bulb.
Once u understand this law, in SPM they always ask u about its application. Where actually do we apply this law??
I'll discuss this on next post :)
I leave u guys a video for u to know more about the owner of this law.
like malay proverb said..
tak kenal maka tak cinta,
..dah cinta, jadi suka..
dah suka, lahir perasaan saling memahami
So the message is..to study physics, u need to fall in love with the subject itself..BUKAN falling in love with your 'bf' or 'gf'.
Once u fall in love with it,..u'll like it more...& understand it better. However u need to do the 1st step..which is knowing it.
..to know it.. u need to studylah :)
Just enjoy yrself while studying physics..
About Me
- Cikgu Ahmad
- I am a full time specialist Physics tutor operating in Klang Valley. I've been educating student for more than 10 years. My specialty is to transform student that had failed their physics subject into a better result. Even some of them managed to get an A in their final exam, You can read their testimony in this blog. I provide home tuition for physics subject to those living nearby KL especially around W.Maju, Ampang,Melawati and Setiawangsa. At the same time i 'm giving online tuition to all malaysia & overseas student. For tuition centre looking for a physics tutor, i'm also able to give seminar and conduct weekly classes. Meanwhile,for school teachers who are organising physics seminar, i am happy to assist u in that aspect. If u have enquiry on my service, do contact or whatsap me at 017-2877589 or email me at celikfizik @ gmail . com
