Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]

Using what you have learned in class, infer which device in the list below would be useful to a geologist because it will align with the lines of force created by Earth’s magnetic field?

A	compass
B	balance
C	telescope
D	seismograph

Explanation:

Detailed explanation-1: -A magnetometer is a device that measures magnetic field or magnetic dipole moment. Different types of magnetometers measure the direction, strength, or relative change of a magnetic field at a particular location.

Detailed explanation-2: -Solution: The device which is used to draw the magnetic field lines is called a compass needle.

Detailed explanation-3: -A compass can be used to detect presence of magnetic field as it will deflect from its N-S direction to direction if magnetic field at that point. Was this answer helpful?

Detailed explanation-4: -At any location, the Earth’s magnetic field can be represented by a three-dimensional vector. A typical procedure for measuring its direction is to use a compass to determine the direction of magnetic North. Its angle relative to true North is the declination ( D ) or variation.
