How does the strength of the magnetic field at the centre of a current carrying circular coil depend on the (i) radim of the coil, (ii) number of turns in the coil, and (iii) strength of the current flowing in the coil ?

Answer»

Solution :(i) INVERSELY PROPORTIONAL, more radius less strong magnetic FIELD.
(ii) Oil.ectly proportional, more turns more strong magnetic field.
(LII)DIRECTLY proportional, more strength of current more strong magnetic field.
