INDUCTION (Try to visualize each of these as you use your right-hand rule) 1)Find the direction of B along the axis of the right-handedly wound solenoid when a) i is increasing b i is steady c)i is decreasing d) Is the figure right-handedly or left-handedly wound? 2)Repeat number 1 if the current is in the opposite direction. a) b) c) 3)This is a loop of wire in the plane of this page with a magnet passing through it. You are looking at the south pole of the magnet as it moves away from you a) What is the direction of i in the loop as the north pole enters the loop? of the magnet enters the loop? pole enters the loop? b)What is the direction of i in the loop as the middle This is the same figure just rotated 90° c)What is the direction of i in the loop as the southExplanation / Answer
I am allowed to answer only 1 at a time.
1st 2 questions are related. SO I will answer 1st 2 questions for you.
1)
B= n*miuo*I
B doesn't depend on the incraesing and decreasing of I, it just depends on the direction of I
As long as I is right handedly, B will be towards left
a) left
b)left
c)left
d)yes
2)
If I is in opposite direction , B will be in opposite direction
B will be towards right
a) right
b)right
c)right
