Choose the correct option:
Intensity of the magnetic field of the earth at the point inside a hollow iron box is ______.
पर्याय
Less than that outside
More than that outside
Same as that outside
Zero
उत्तर
Intensity of the magnetic field of the earth at the point inside a hollow iron box is zero.
Explanation:
Because the intensity of the magnetic field inside a hollow iron box is zero. Even iron is a ferromagnetic material but it only attracts the magnetic field in the material, not in any hollow part.
