Question

State the factors on which the strength of magnetic field due to a straight current carrying conductor depend

Answer 1

It is directly proportional to the current passing in the wire and inversely proportional to the distance of that point from the wire. so, greater the current in a wire, stronger will be the magnetic field produced. and greater the distance of a point from the current carrying wire,weaker will be the magnetic field produced at a point.

Answer 2

HI MATE HERE IS YOUR ANSWER ;

On increasing the strength of current in the conducting while the number of field lines around it increases space between the field lines decreases in other words the strength of magnetic field is directly proportional to current passing through it the it is also observed that the strength of the magnetic field is inversely proportional to the distance from the conductor hands with an increase in the distance from the conductor the strength of magnetic field decreases.
