Explain with reference to d-block elements: magnetic property.

What are p-block elements ?

What are s-block elements ?

Which element belongs to d-block elements ?

Explain three magnetic elements of earth's magnetic field at a given place.

A magnet is suspended vertically from a fixed point by means of a spring, as shown in the figure. One end of the magnet hangs inside a coil of wire. The coil is connected in series with a resistance R. The magnet is displaced vertically a small distance D and the released. shown in the figure variation with time t of the vertical displacement d of the magnet from its equilibrium position. State and explain, by reference to electromagnetic induction, the nature of the oscillations of the magnet. Calculate the angular frequency omega_0 of the oscillations.

How many groups are there in d-block element?
