If a magnet of pole strength $m$ is divided into four parts such that the length and width of each small part is half that of initial one, then the pole strength of each parts will be

A long magnetic needle of length $2l$ magnetic moment $\mathit{M}$ and pole strength $m$ is broken into two pieces at the middle. The magnetic moment and pole strength of each piece will be

The horizontal component of the earth's magnetic field at a place is $0.25\times {10}^{-4}\mathrm{Wb}/{\mathrm{m}}^2$ and its vertical component is $0.35\times {10}^{-4}\mathrm{Wb}/{\mathrm{m}}^{-4}$. Then the earth's total magnetic field at that place is

The North pole of Earth's magnet is near the geographical

The unit of magnetic flux density is
