The variation of magnetic susceptibility $(\chi)$ with temperature for a diamagnetic substance is best represented by
1
2
3
4
Explanation:
B For a diamagnetic substance susceptibility is small and negative and it is independent of temperature. So, curve should be in negative direction with constant value of graph.

Select the correct statement from the following
1 The magnetic dip is zero at the centre of the earth
2 Magnetic dip decreases as we move away from the equator towards the magnetic pole
3 Magnetic dip increases as we move away from the equator towards the magnetic pole
4 Magnetic dip does not vary from place to place
Explanation:
C At equator, magnetic dip angle $\delta=0^{\circ}$ At poles, $\delta=90^{\circ}$ Magnetic dip angle increases as we move away from the equator toward the magnetic poles.

A very long conductor carries a current of $1 \mathrm{~A}$. The magnetic field at a point whose distance is $0.1 \mathrm{~m}$ from one end of the conductor is (in ' $\mathrm{T}$ ')
1 $10^{-6}$
2 $2 \times 10^{-6}$
3 $10^{-3}$
4 $10^{-2}$
Explanation:
A Given that, I = $1 \mathrm{Amp}$ $\mathrm{r}=0.1 \mathrm{~m}$ Then magnetic field from one end of conductor $\mathrm{B}=\frac{\mu_{0} \mathrm{I}}{4 \pi \mathrm{r}}=\frac{4 \pi \times 10^{-7} \times 1}{4 \pi \times 0.1}$ $\mathrm{~B}=10^{-6} \mathrm{~T}$
