❗️Electric fields are created by single charged particles and depend on the amount of charge inside an object.
⚡️Electric field lines extend to infinity and are strongest near the charged particle.
🔌The number of electric field lines leaving an object is determined only by the amount of charge inside.
🧲Magnetic fields are different from electric fields and depend on moving charged particles.
🔄Changing electric fields create magnetic fields, and changing magnetic fields create electric fields.
