answered-by-expert Expert Answer
 

Current flowing through wire : If current is increased then deflection of needle of magnetic compass placed inside wire also increases.

i.e Strength of magnetic field is directly proportional to current.

- Radius of circular wire : Strength of magnetic field is inversely proportional to radius of circular wire.

- Number of turns in circular wire: If number of turns in circular wire are increased,Magnetic field at the centre of loop increases.
