In an electric magnet there is an ordinary metal used which when you run a current through it, induces a magnetic field, the permanent magnet (usually made of lodestone) contains particles which are already arranged in a manner that produces a magnetic field.
Magnetic fields are created by permanent magnets or electric currents, while electromagnetic fields are created by electric currents. Electromagnetic fields are more complex and can change over time, while magnetic fields are static.
The main difference between mechanical and electromagnetic waves is how they travel. Mechanical waves require a medium, such as air or water, to propagate, while electromagnetic waves can travel through a vacuum.
The primary difference between mechanical and electromagnetic waves is how they travel. Mechanical waves require a medium, such as air or water, to propagate, while electromagnetic waves can travel through a vacuum, like in space.
The main difference between mechanical and electromagnetic waves is that mechanical waves require a medium (such as air or water) to travel through, while electromagnetic waves can travel through a vacuum (empty space) because they do not require a medium.
The difference between types of electromagnetic radiation, such as radio waves, visible light, or X-rays, is determined by their frequency and wavelength. Electromagnetic radiation with higher frequency and shorter wavelength has more energy and is more harmful to biological tissues. The electromagnetic spectrum encompasses all these types of radiation.
