... We would have to work on the current loop in order rotate the loop so that its magnetic field was no longer aligned with the external magnetic field. If we release the current loop, the external magnetic field will do work on our current loop to realign the fields. Thus, magnetic potential energy wa ...

How To Find the Induced EMF in a Loop Using Faraday`s Law and
... Faraday’s Law and Lenz’s Law Actually, problems involving induction tend not to be so amenable to a simple “how-to”: in general, they vary a lot in terms of what you are asked to find for the final answer, and in terms how you are expected to use the induced EMF or current. However, there are some s ...

Magnetometer
Magnetometers are measurement instruments used for two general purposes: to measure the magnetization of a magnetic material like a ferromagnet, or to measure the strength and, in some cases, the direction of the magnetic field at a point in space.The first magnetometer was invented by Carl Friedrich Gauss in 1833 and notable developments in the 19th century included the Hall Effect which is still widely used.Magnetometers are widely used for measuring the Earth's magnetic field and in geophysical surveys to detect magnetic anomalies of various types. They are also used militarily to detect submarines. Consequently, some countries, such as the USA, Canada and Australia classify the more sensitive magnetometers as military technology, and control their distribution.Magnetometers can be used as metal detectors: they can detect only magnetic (ferrous) metals, but can detect such metals at a much larger depth than conventional metal detectors; they are capable of detecting large objects, such as cars, at tens of metres, while a metal detector's range is rarely more than 2 metres.In recent years magnetometers have been miniaturized to the extent that they can be incorporated in integrated circuits at very low cost and are finding increasing use as compasses in consumer devices such as mobile phones and tablet computers.
