Why does a current carrying conductor kept in a magnetic field experience force? On what factor does the direction of this force depend? Name and state the rule used determination of direction of current
The current carrying conductor has its own magnetic field when it superimpose the magnetic field of the magnet the attract or repel each other so it experiences the force.
The rule used for finding direction of current is Fleming's right hand rule:
When fore finger , middle finger,and the thumb stretched mutually perpendicular to each other and the fore finger is denoted by magnetic field and the force is denoted by the thumb then the current flowing through the conductor is denoted by middle finger.
