T = IAB sin θ ; θ is the angle between B and I.
T = μ × B
The Attempt at a Solution
A) T = IAB sin θ
T = √2 a b I B (θ = 45°)
B) T = 0 , because θ = 0
C) T = 0 , because θ =180°
D) T = μ × B
The direction of μ = k , because the fingers points to the direction of current and the thump points to the direction of T.
T = (k) × (k)
=0
E) T = (k)×(k)
=0
So , the answer is 'A' .
Is it correct ?
