The force between two magnetic poles in air is `9*604mN`. If one pole is 10 times stronger than the other, calculate the pole strength of each. Given distance between two poles=`10cm`.

Answer

`9*8Am`; `98Am`

Explanation

Here, `F=9*604mN=9*604xx10^-3N`
If `m_1=m`, `m_2=10m`, `r=10cm=0*1m`
As `F=(mu_0)/(4pi)(m_1m_2)/(r^2)`
`:. 9*604xx10^-3=10^-7(m(10m))/((0*1)^2)`
`m^2=96*04`, `m=9*8Am`
`:. m_1=9*8Am, m_2=10m=98Am`.
