Vedclass · Answer

(D) $1$. The angle of dip at the magnetic poles is $90^o$,which is correct.$2$. Cosmic particles (charged particles) are deflected by the Earth's magnetic field. They are guided towards the poles,meaning they can reach the magnetic equator if they have sufficient energy,or they are generally deflected away from the equator compared to the poles. The statement that they can 'never' reach the magnetic equator is physically incorrect as it depends on their energy and trajectory.$3$. The density of cosmic particles is indeed maximum at the magnetic poles because the magnetic field lines converge there,guiding charged particles into the atmosphere.$4$. The magnetic meridian is a vertical plane passing through the magnetic axis,not a straight line. Therefore,option $D$ is incorrect.
