Alarm to catch thieves.

my avvy is stolen by the thief FLRNAB
I will have to change it

-Max number of magnetic field lines being cut
-Cutting at the fastest rate
-Change in Magnetic flux is greatest
-Emf is greatest when change is magnetic flux is greatest

Max no. of magnetic field lines being cut and change in magnetic flux is the same.
This question is infact of only 2 marks (it has come in a recent paper)

 

[Awesome12]

Why induced emf is greatest when the coil is in horizontal position? (4 marks)
Anyone?

Although this is a 2 mark question, I think it will be like this;

Maximum no. of magnetic field lines are being cut
In a unit time
The faster cutting of the field lines
Results in the greatest rate of change of the magnetic field lines

Rate of change of magnetic flux no?

How's prep everyone?

I'm going to start studying physics. Spent the day studying Sociology. :/
Just solved a few paper 1's for Physics yesterday. .-.
No paper 2's.. .-.
