Intensity of magnetic field due to earth at a point inside a hollow steel box is

Intensity of magnetic field of the earth at a point inside a hollow iron box is ______.

Explain the terms the magnetic field due to earth at a point.

Assertion: Intensity of magnetic field due to a solenoid near its ends is only half of its magnitude inside the solenoid. Reason: If solenoid is made very long then magnetic field inside the solenoid becomes uniform.

The intensity of magnetic field due to a short bar magnet at a given point on its axis inversely proportional to_________

(a)Using Ampere's circuital law, obtain the expression for the magnetic field due to a long solenoid at a point inside the solenoid on its axis. (b )How is the magnetic field inside a given solenoid made strong?

What is the value of Electric field intensity at any point inside a charged hollow spherical conductor?
