प्रश्न
Name and state the rule to find the direction of:
current induced in a coil due to its rotation in a magnetic field.
उत्तर
Fleming's right-hand rule will be used to find the direction of induced current here. According to this rule, when right hand's thumb, forefinger and centre finger are held mutually perpendicular to one another, the thumb represents the direction of motion of the coil, the forefinger represents the direction of the magnetic field and the centre finger represents the direction of the induced current.

Given below is a circuit to study the magnetic effect of electric current. ABCD is a cardboard kept perpendicular to the conductor XY. A magnetic compass is placed at the point P of the cardboard. P1 and P2 are the positions of the magnetic compass, before and after passing a current through XY respectively.
