What are the differences between these three types of fields or are they all interrelated and the same.

Magnetic field: a 3-vector: (Bx, By, Bz)
Electromagnetic field: a 2-form (with 6 components): (Ex, Ey, Ez;Bx, By, Bz)

Electric, magnetic, and electromagnetic fields are forms of energy that are created by the movement of charged particles, such as electrons. Electric fields are created by stationary charges, while magnetic fields are created by moving charges. Electromagnetic fields are a combination of electric and magnetic fields, and they can travel through space as waves.
Electric and magnetic fields are present in many aspects of our daily lives, from the devices we use to the natural world around us. They are essential for the functioning of electronic devices, such as phones and computers. They also play a crucial role in the Earth's magnetic field and the generation of electricity.
There is ongoing research on the potential health effects of exposure to electric and magnetic fields. While there is no conclusive evidence that they are harmful, some studies suggest a possible link between long-term exposure to high levels of electromagnetic fields and certain health conditions. However, the levels of electric and magnetic fields in our daily lives are generally well below the safety limits set by regulatory agencies.
To reduce exposure to electric and magnetic fields, it is recommended to keep a safe distance from high-voltage power lines and to limit the use of electronic devices. Shielding materials can also be used to reduce the levels of electric and magnetic fields in specific areas, such as homes or offices.
Yes, electric and magnetic fields can be harnessed to generate electricity. This is the principle behind power plants that use turbines to convert the energy from moving water or steam into electricity. Renewable energy sources, such as solar and wind power, also use electric and magnetic fields to generate electricity.
