Answer:
(C) Either no magnetic field exists or the particle is moving parallel to B.
Step-by-step explanation:
- The moving charged particle tends to show no magnetic forces. Due to its moving in the same direction and will be parallel to the field.
- As when the magnetic fed and charged particle velocity is parallel then there will be no force.
- As the magnetic field are made by the generation of the current with the field line concentric to the current-carrying wire.
