01.) An electric current in a magnetic field will experience a force
Freshchat
2.) If the current carrying wires are bent into a loop when the two sides of the loop which are at right angles to the magnetic field will experience forces in opposite direction.
3.) The pair of forces creates a turning influence or torque to rotate the coil.
4.) Particle motors have several loops on an armature to provide a more uniform torque.

a. When the armature coil ABCD rotates in the magnetic field provided by the strong magnets, it cuts the magnetic lines of forces.
b. Thus the changing magnetic field produces induced current in the coil. The direction of induced current is determined by the Flemings right hand rule.
c. The current flows out through the brush B1 in one direction in the first half of the revolution and through the brush B2 in the next half revolution in the reverse direction, this process is repeated.
d. Therefore, the induced current produced is of alternating nature. Such a current is called as alternating current.
