โAn electron always experiences a force in an electric field, but not always in a magnetic field.โ Defend this statement. 1. Away from the Earth an electron does not feel any magnetic force. 2. If the velocity of an electron is greater than a critical value, a magnetic field cannot exert any force on the electron. 3. Sometimes a magnetic field disappears when an electron is placed in it. 4. An electric field always acts on charged particles. The magnetic force vanishes when the velocity of the electron is parallel to the magnetic field. 5. An electron always has a charge in an electric field, but not always in a magnetic field.
