Ditto Radio and the half circles in a white quad are tuning capacitors.

It's a radio am by the looks. The component you circle is the antenna. The ferrite core concentrates the rd signal to improve the performance of the wire cool that forms the tuned circuit.

Ferrite will not make a good magnetic core because the ferrite particles are small resulting in small magnetic fields

and, sadly, I have found that it doesn't make very good electromagnets.
