Answer:
Induced emf,
Explanation:
Given that,
Length of the helicopter, l = 4 m
Angular speed of the helicopter,
The vertical component of the Earth’s magnetic field is,
We need to find the induced emf between the tip of a blade and the hub. The induced emf in terms of angular velocity of an rotating object is given by :
So, the induced emf between the tip of a blade and the hub is . Hence, this is the required solution.
Answer:
initial magnetic field 1.306 T
Explanation:
We have given area of the conducting loop
Emf induced = 1.2 volt
Initial magnetic field B = 0.3 T
Time dt = 0.087 sec
We know that induced emf is given by
So initial magnetic field = 1.606-0.3= 1.306 T
