Magnetic fields refer to the regions around a magnet or an electric current in which magnetic forces can be observed. They are represented by magnetic field lines that indicate the direction and strength of the magnetic force. The strength of a magnetic field is measured in teslas (T) or gauss (G), with one tesla equating to 10,000 gauss. Magnetic fields are generated by magnetic materials, by moving electric charges, or by time-varying electric fields, according to Maxwell’s equations.
In everyday life, magnetic fields are significant in various applications, including electric motors, transformers, magnetic storage devices, and medical imaging techniques like MRI (Magnetic Resonance Imaging). They play a crucial role in understanding phenomena in physics, engineering, and technology, influencing the behavior of charged particles and conducting materials within the field.
The existence of a planet's magnetic field has long been recognized as a crucial factor in determining its habitability. Earth, with its strong magnetic field, is shielded from high-energy particles…
