Hello,

Magnetic dip or magnetic inclination at a place is defined as the angle which the direction of the total strength of the earth’s magnetic field makes with horizontal line in magnetic meridian

At different places on the surface of the earth Magnetic Dip is different. At the two magnetic poles, the magnetic needle rests vertically. Therefore, angle of dip at the two poles is 90°. On the magnetic equator, the angle of dip is 0° as the needle would rest horizontally at the magnetic equator. At other places the value of dip angle lies between 0 and 90 degrees.

Therefore, the angle of dip from equator to the poles varies from 0° to 90°.

Best Wishes.
