Answer:
moving the circuit or the magnet gives the same result
Explanation:
The faraday effect establishes that the temporal variation of imaginative flow produces an electric potential
fem = dfi / dt
the magnetic flux is
Ф = B. A = B A cos θ
suppose for simplicity that the angle is zero so cos 0 = 1
Φ = B A
By analyzing this expression, the change in magnetic flux can converge while keeping the magnetic field fixed and varying the electric field or keeping the electric field fixed and varying the magnetic field.
Consequently moving the circuit or the magnet gives the same result

solution solved below
Answer:
a) 14M
Explanation:
a)The inertia of a particle moving in a circular axis is given by,
I = Moment of inertia
M = mass of the particle
r = perpendicular distance from axis of rotation.
And by adding moment of inertia of each particle we can come to the moment of inertia of the system.
I = M+M
+M
+M
= 14M
b) Your question is incomplete but I'll write how to find the minimum force required to give a system given angular acceleration.
Minimum force is found when applied from the furthest point to the axis of rotation in the system.
, by τ = Fr, whereτ = torque , F = Force , = perpendicular distance from axis of rotation.
For minimum force r = 3d
And also τ = Iα where I = Moment of inertia and α = angular acceleration
By combining the two equations you get minimum force as,
F = Iα/r
F' = 14Mα/3d
= 14Mαd/3
