At the magnetic equator of the Earth, what is the value of the angle of dip?
0°
The angle of dip is the angle that the Earth's total magnetic field makes with the horizontal plane at a given location.
At the magnetic poles, the field is entirely vertical, so the angle of dip is \(90°\).
At the magnetic equator, the Earth's magnetic field lines run parallel to the surface, that is, purely horizontal, so the field makes no angle with the horizontal.
Hence, the angle of dip at the magnetic equator is \(0°\).
A substance that is weakly attracted when placed in an external magnetic field and does not retain magnetization after the field is removed is classified as :
The magnetic force on a charged particle moving parallel to a uniform magnetic field is:
