Working Principle of D.C Motor
A) An electric motor is a machine which changes electrical energy into mechanical energy.
B) When a current carrying conductor is placed in a magnetic field, it experience a mechanical force whose way is given by " Flemings Left hand rule" & magnitude is given by F= B.I.L Newton
C) When field magnets are excited and armature conductors are supplied with current from supply main, they experience a force tending to move the armature. Armature conductors under N-Pole are supposed to carry current in (crosses) and those under S-Pole to carry current out (dots).
An electric iron draws a current of 0.5A.The voltage is 200V. Calculate the amount of charge flowing through it in 1 hour.

Can the whole charge of a body is transfer to another body
At the neutral position, magnetic field because of the bar magnet is just equal and opposite to the horizontal component of earth's magnetic field.
Displacement: - The modification in position of a body in a particular direction is called as displacement. It is a vector function and its unit in SI system is meter. Distanc
