A Comprehensive Guide to Buying a Magnetometer

Your Guide to buying the best Magnetometers

Overview

A magnetometer is an instrument that is used to measure magnetic fields. Magnetic fields are invisible, but they are present everywhere in the environment and can be used to measure a variety of phenomena including geomagnetic storms, navigation, and more. This buying guide will help you understand the different types of magnetometers and the features to consider when selecting the best option for your needs. We will discuss the types of magnetometers, how to measure your specific needs, and what to look for in terms of features and accuracy. Additionally, we will provide helpful tips for choosing and using the right magnetometer for the job.

Key features

  1. Purpose: What is the purpose of the magnetometer? Is it for scientific research, navigation, or some other task? Knowing the intended use can help you select the right magnetometer for the job.
  2. Sensitivity: How sensitive is the magnetometer? More sensitive magnetometers will be able to detect weaker magnetic fields.
  3. Sensor Type: What type of sensor is used in the magnetometer? This can affect the accuracy of the measurements taken.
  4. Portability: How portable is the magnetometer? Some magnetometers are built to be hand-held, while others are too large or delicate to be moved easily.
  5. Power Requirements: Does the magnetometer need an external power source or can it operate autonomously?
  6. Cost: What is the cost of the magnetometer? This is usually the most important factor for most consumers.
  7. Support: Does the manufacturer offer technical support? This can be important if there are any problems with the magnetometer.

Important considerations

Pros

  • Accuracy: Magnetometers are able to accurately measure magnetic fields in both 2 and 3 dimensions, which can be beneficial for a variety of applications.
  • Delicate Measurements: Magnetometers are also able to take very delicate measurements, such as those of very small changes in the magnetic field.
  • Compact Size: Magnetometers are relatively small in size, which makes them easy to transport and use in different environments.
  • Cost-effective: Magnetometers are also relatively cost-effective and require minimal maintenance.
  • Versatility: Magnetometers are highly versatile and can be used in a wide range of applications, such as sensing, navigation, and geomagnetism.

Cons

  • Price: Magnetometers can be expensive, depending on the type and the features that they offer.
  • Accuracy: Magnetometers are not 100% accurate and may require calibration to achieve the best accuracy.
  • Interference: Magnetometers can be affected by electrical and magnetic fields in the environment, which can cause inaccurate readings.
  • Sensitivity: Magnetometers may not be able to detect weak magnetic fields, which can limit their use in certain applications.
  • Size and Weight: Depending on the type, Magnetometers can be bulky and heavy, which can make them difficult to transport and handle.

Trivia

A funny fact about magnetometers is that they were once used to find a long-lost treasure. In the 1990s, archaeologists in Sweden used a magnetometer in the search for the legendary 17th century Swedish warship, Vasa. After a few months of scanning the seafloor, the magnetometer located the ship’s metal hull, which had been buried in mud for centuries. After being raised from the seabed, the Vasa is now on display at the Vasa Museum in Stockholm, and has become one of Sweden’s most popular tourist attractions.
