Answer:

(i) Maxwell's right-hand thumb rule: Magnetic field produced around a straight conductor carrying current.If the thumb of the right-hand points along the direction of the current, then the remaining curled fingers of the same hand give the magnetic field direction due to the current.

(ii) Fleming's left-hand rule: Force experienced by a current-carrying straight conductor placed in a magnetic field which is perpendicular to it. Whenever a current-carrying conductor comes under a magnetic field, there will be a force acting on the conductor.

(iii)If the forefinger points in the direction of the magnetic field, the central finger in the direction of current, then the thumb points in the direction of force in the conductor.Fleming's right hand rule gives the direction of induced current in a coil due to it's rotation in amagnetic field.

(iv)A coil of many circular turns of insulated copper wire wrapped closely in the shape of a cylinder is called a solenoid. The pattern of the magnetic field lines around a current-carrying solenoid is illustrated.This indicates that the magnetic field is the same at all points inside the solenoid.
