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
Answer:
Explanation:
From the vertical movement, we know that initial speed is 0, and initial height is H, so:
solving for t:
Now, from the horizontal movement, we know that initial speed is V and the acceleration is -g/4:
Replacing values:
Simplifying:
