Question
The figure shows an isosceles triangle wire frame with apex angle equal to π/2. The frame starts entering into the region of uniform magnetic field B with constant velocity v at t = 0. The longest side of the frame is perpendicular to the direction of velocity. If i is the instantaneous current through the frame then choose the alternative showing the correct variation of i with time.
Options
A.
B.
C.
D.
Solution
Area in the magnetic field is given by
A = x2; f = Bx2
= 2Bx
= 2Bvx
i =
, i ∝ t
A = x2; f = Bx2
= 2Bx = 2Bvxi =
, i ∝ tCreate a free account to view solution
