AIIMS 2018 | Magnetism and Matter Question 3 | Physics

The horizontal component of the earth's magnetic field at any place is $$0.36 \times 10^{-4} \mathrm{~Wb} / \mathrm{m}^2$$. If the angle of dip at that place is $$60^{\circ}$$, then the value of vertical component of the earth's magnetic field will be (in $$\mathrm{Wb} / \mathrm{m}^2$$ )

$$0.12 \times 10^{-4}$$

$$0.24 \times 10^{-4}$$

$$0.40 \times 10^{-4}$$

$$0.622 \times 10^{-4}$$

The angle of dip, if dip needle oscillating in vertical plane makes 40 oscillations per min in a magnetic meridian and 30 oscillations per minute in vertical plane at right angle to the magnetic meridian is

$$\theta=\sin ^{-1}(0.5625)$$

$$\theta=\sin ^{-1}(0.325)$$

$$\theta=\sin ^{-1}(0.425)$$

$$\theta=\sin ^{-1}(0.235)$$

Assertion : The magnetism of magnet is due to the spin motion of electrons.

Reason : Dipole moment of electron is smaller than that due to orbit motion around nucleus.

Both assertion and reason are true and reason is the correct explanation of assertion

Both assertion and reason are true but reason is not the correct explanation of assertion

Assertion is true but reason is false
