Two north poles each of pole strength $m$ and a south pole of pole strength $m$ are placed at the three corners of an equilateral triangle of side $a$ . The intensity of magnetic induction field strength at the centre of the triangle is

Options:

Answer:

Solution:

$B_{r e s} = 2 B$

where, $B = \frac{μ_{0}}{4 π} \frac{m}{{(\frac{a}{\sqrt{3}})}^{2}}$

$\Rightarrow B_{res} = 2 \times \frac{μ_{0}}{4 π} \frac{m}{{(\frac{a}{\sqrt{3}})}^{2}} \Rightarrow B_{res} = \frac{3 μ_{0}}{2 π} \frac{m}{a^{2}}$
