Magnetic Field Lines: Magnetic field is an important topic in physics, which starts to elaborate at the secondary level. CBSE introduces this topic in Class 10 and then dives into details in further ...

Traditionally, scientists believed that the charge polarity of the magnetosphere at the equator and the poles was the same, ...

This means that their magnetism is there all the time and cannot be turned on or off as it can with an electromagnet. Converting a magnet to a non-magnet is called demagnetisation. Magnets are made ...

High frequency Helmholtz coils are often used to generate uniform but time varying high frequency magnetic fields for a number of applications such as magnetic field susceptibility, calibration, and ...
