The magnetic field strength at a point at a distance 'd' from ...
For short bar magnet Baxial= u 2M/4pi× d^3.
and Beq= uM/4pi× d^3=> u 8M/4pi× (2d)^3= uM/4pi× d^3.
comparing Both equation we get Beq= Baxial/2.
and Beq= uM/4pi× d^3=> u 8M/4pi× (2d)^3= uM/4pi× d^3.
comparing Both equation we get Beq= Baxial/2.

The magnetic field strength at a point at a distance 'd' from ...
Explanation:
Given, magnetic field strength at a distance d from the centre of a very short bar magnet of magnetic moment M is B.
1. Magnetic field strength at a point on the axial line of a magnet:
The magnetic field strength at a point on the axial line of a magnet is given as:
B = (μ₀/4π) × (2M/d³)
Where, μ₀ is the permeability of free space, M is the magnetic moment of the magnet and d is the distance from the centre of the magnet.
Using the above equation, we get:
B = (μ₀/4π) × (2M/d³)
2. Magnetic induction at a distance 2d from the centre on the equatorial line of a magnet:
The magnetic induction at a distance 2d from the centre on the equatorial line of a magnet is given as:
B' = (μ₀/4π) × (8M/4d³)
Where, μ₀ is the permeability of free space, 8M is the magnetic moment of the magnet and 4d is the distance from the centre of the magnet.
Using the above equation, we get:
B' = (μ₀/4π) × (8M/4d³)
Simplifying the above equation, we get:
B' = B/2
Therefore, the magnetic induction at a distance 2d from the centre on the equatorial line of a magnet of moment 8M will be B/2.
Hence, option B is the correct answer.

B' = (μ₀/4π) × (8M/4d³)
Where, μ₀ is the permeability of free space, 8M is the magnetic moment of the magnet and 4d is the distance from the centre of the magnet.
Using the above equation, we get:

Therefore, the magnetic induction at a distance 2d from the centre on the equatorial line of a magnet of moment 8M will be B/2.
Hence, option B is the correct answer.
