Magnetic field can be plotted with the help of a compass needle.

A magnetic field line is a line in a magnetic field, tangent to which at any point gives the direction of the magnetic field.

Angle of dip is the angle made with the horizontal by the earth's total magnetic field.

Angle of declination is the angle between magnetic meridian and geographic meridian at that place.

Words to Remember:-

Amalgamation; Angle of dip; Angle of declination; Demagnetization; Geographic meridian; Lines of force; Magnet; Magnetic meridian; Magnetic field; Magnetic pole; Magnetization; Neutral point.
