Electromagnetism is a very common theory that we hear in electrical engineering. Many electrical concepts revolve around electromagnetism. As the term defines, it is a combination of electricity and magnetism. Two common terms related to both of them are electric field and magnetic field.
In this post, we will learn about the basics and understand the difference between electric fields and magnetic fields.
You know a magnet has two poles – north and south. Magnets either attract or repel. Also, if a north pole is placed around the south pole, then it will attract and if a north pole is placed around the north pole, it will repel. This region around the magnet where the poles either attract or repel is called a magnetic field.
Basically, in a magnet, a magnetic field is produced either in a natural way as discussed before or also through a passing electric current (moving electrical charges).
When electric charges move across space or an electrical conductor, a magnetic field is induced due to its motion. So, whenever a metallic object like iron comes in the range of this magnetic field, the magnet pulls the iron towards it.
You know that an atom has a proton (positively charged) and an electron (negatively charged). Basically, every conducting atom has an electric field around it. This is due to the presence of these two components.
Positive charges are drawn towards it, while negative charges are repelled. So, it can also be defined as a force surrounding an electrically charged particle.
The main differences between electric and magnetic fields are mentioned below.
In this way, we understand the difference between a magnetic field and an electric field.
