An electric field is generatit bi electrically charged pairticles an time-varyin magnetic fields. The electric field describes the electric force experienced bi a motionless positively electrically charged test pairticle at ony pynt in space relative tae the soorce(s) o the field. The concept o an electric field wis introduced bi Michael Faraday.

Electric field lines emanatin frae a pynt positive electric charge suspendit ower a negatively charged infinite sheet
