Hint :In order to answer this question, we need to understand that the current in the conductor is due to the motion of free electrons in a definite direction. When such a conductor/wire is placed in the magnetic field, each electron moving in this field experiences a force. Thus, the current-carrying wire/conductor experiences a force in the magnetic field.
Complete Step By Step Answer:
A stationary charge produces an electric field around it while flow of charge or current produces a magnetic field around it. (The direction of the magnetic field around a current carrying wire is given by the Right hand thumb rule.) Experimentally, it is observed that when a current carrying conductor is placed in an external magnetic field then the conductor experiences a force.
The direction of this magnetic force is directly dependent on:
(1). Direction of current flowing through the conductor
(2). Direction of external magnetic field
When a current carrying conductor having no net charge is placed in a magnetic field, the free electrons of the conductors move towards the positive end of the conductor with the same drift velocity, hence a magnetic force acts on them. The positive ions of the conductor being stationary, do not experience any magnetic field.
Hence, the correct option is (B).
Note :
It should be remembered that the given statement has an alternative concept. For this, we must know that a current carrying conductor acts as a magnet. When a magnet is placed in a magnetic field, the magnet experiences a magnetic force. Therefore, a current carrying conductor will also experience a magnetic force, since it acts as a magnet.
