Question
Two different wire loops are concentric and lie in the same plane. The current in the outer loop $$\left( I \right)$$ is clockwise and increases with time. The induced current in the inner loop
Two different wire loops are concentric and lie in the same plane. The current in the outer loop $$\left( I \right)$$ is clockwise and increases with time. The induced current in the inner loop
A.
is clockwise
B.
is zero
C.
is counter clockwise
D.
has a direction that depends on the ratio of the loop radii.
Answer :
is counter clockwise
Solution :
As $$I$$ increases, $$\phi $$ increases
∴ $${I_i}$$ is such that it opposes the increases in $$\phi .$$ Hence, $$\phi $$ decreases (By Right Hand Rule). The induced current will be counterclockwise.
