A bar magnet has length $$3 \mathrm{~cm}$$, cross-sectional area $$2 \mathrm{~cm}^2$$ and magnetic moment $$3 \mathrm{~Am}^2$$. The intensity of magnetisation of bar magnet is

The relative permeability of iron is 2000. Its absolute permeability in SI unit will be $$\left(\frac{\mu_0}{4 \pi}=10^{-7} \text{SI unit}\right)$$

The permeability of a metal is $$0.1256 ~\mathrm{TmA}^{-1}$$. Its relative permeability will be $$\mathrm{\left( {{{{\mu _0}} \over {4\pi }} = {{10}^{ - 7}}\,SI\,unit} \right)}$$ ($$\pi=3.14$$)

The north pole of a long horizontal bar magnet is being brought towards closed circuit consisting of a coil. The direction of induced current produced in it is
