Question

At magnetic poles, the angle of dip is

• A. ${45}^o$
• B. ${30}^o$
• C. zero
• D. ${90}^o$

Answer 1

Answer: (D)

${90}^o$

Magnetic dip results from the tendency of a magnet to align itself with lines of force. As the Earth's magnetic lines of force are not parallel to the surface, the north end of a compass needle will point downward in the northern hemisphere (positive dip) or upward in the southern hemisphere (negative dip). The range of dip is from -90 degrees (at the south magnetic pole) to +90 degrees (at the north magnetic pole).
