B Main difference between electrostatics and magnetism

  1. Sep 12, 2016 #1
    Electromagnetism is divided into two parts
    1. Electrostatics
    2. Magnetism
    • Therefore I want to know what are the main difference between electrostatics and magnetism with their examples in layman terms because I am not at all introduced to this concept but I want to know the general concepts related to this. Thanks in advance.

    The basic idea is that electrostatics is the study of static (unchanging) electric fields, electric charges, and the rules governing their interactions. Magnetism is the study of static magnetic fields, magnets, and the rules for their interactions. The two areas are tied together with electrodynamics, which is the study of changing electric and magnetic fields and EM waves.

    Can you describe some phenomena that you are not sure about whether they fall under "electrostatics" or "magnetism"?

    I Think lightning, attraction of ballon to wools , comb to paper pieces , force between surface , tension are example of electrostatics , I know that charges are responsible for electrostatic phenomenons but what is responsible for magnetism , what about carriers ,
    somewhere it is written that electrons are carriers of electrostatic force and photons are for magnetic force,I need more information on magnetic force, how they occurs.

    Put simply, magnetic fields are created by moving electric charges. This also includes the contribution from a particle's spin, which commonly manifests in ferromagnetism due to unpaired electrons. A moving electric charge will generate a magnetic field, as any electromagnet demonstrates, and other electrically charged particles will react to this magnetic field if they are moving relative to it (or the field is changing).

    Off to school. I'll try to respond later on today/tonight if I can. Busy busy!

    Wohoooo , thank you sir , I think you want to say that electrostatic is when charges are at rest and formula to caculate force is coulums law and magnetism is phenomena when charges are in motion , I think I got the main difference, once agin thank you so much
    And formula for magnetic force is not only columbs law but it is different or some more part in the same formula

    The equivalent of Coulomb's law for magnetic fields is the Biot-Savart law.
