Question

the ratio of magnetic induction along the axis to magnetic induction along the equator of a magnet is​

Answer 1

Given:

A bar magnet

To find:

The ratio of magnetic induction along the axis to along the equator of a magnet.

Solution:

• Magnetic induction at axial point = Baxial = μ₀​2m / 4πr³

• ​Magnetic induction at equatorial point = Bequ = μ₀​m / 4πr³

• ​Also, μ = 4π x 10⁻⁷ TmA⁻¹

• Dividing Baxial and Bequ, we get,

        Baxial / Bequ = 2 / 1

• Thus, the ratio of magnetic induction due to a bar magnet on its axial point and the equatorial point is 2:1.
