The motion of a charged particle can be used to distinguish between a magnetic field and electric field in a certain region by firing From opposite directions
If charged particle is parallel to field it will go undeflected straight This may be due to either of electric or magnetic field and we won't be able to distinguish between the fields If we fire perpendicularly also deflection may be due to both fields Firing with different speeds does not effect direction of deflection If we fire from opposite directions, then for electric field deflection will be in same direction But for magnetic field direction of deflection is reversed That's why firing from opposite directions will show that if the field is electric field or magnetic field. By shooting from different directions, a charged particle may be utilized to discriminate between an electric and magnetic field in a specific area.
