The correct answer is: FE = √3 FB
At neutral points, the magnetic field due to the Earth (FE) is equal to the magnetic field due to the magnet (FB) multiplied by the square root of 3.
This is because the neutral points are located where the magnetic field of the Earth and the magnetic field of the magnet are equal in magnitude and opposite in direction, resulting in a net magnetic field of zero. The relationship between the two fields at these points is given by the equation FE = √3 FB.
