Magnetometers:

Magnetometers are measurement instruments used to measure the magnetization of a magnetic materials, measure the strength and the direction of the magnetic field at a point in space.

Magnetometers are generally used for measuring the Earth's magnetic field to detect magnetic anomalies of various types, and also used in military to detect submarines.

In recent days, the magnetometers are used as compasses in consumer devices such as tablet computers and mobile phones.

Laboratory type magnetometers are used to measure the magnetization (magnetic moment) of a sample placed inside the magnetometers. We shall cover different types of magnetometers used for detecting magnetic moment of the samples and see how to obtain various factors by performing magnetic measurements as a function of applied field, temperature, time.
