Question

The value of the magnetic field at adistance x from a long straight current carrying conductor is proportional

Answer 1

Hey MATE!!

In general magnetic feild (B)is :

> Directly proportional to current in

element (i.dl),

> Directly proportional to angle between the point where we are measuring B and where the current in elemnt is taken and

> Indirectly proportional to the square of distance between current element and position vector of point.

In case of current carrying straight long wire :

1) Directly proportional to current

2) Angle where current element is and and reference point and

3) Inversely proportional to distance between current element and reference point.

Hope it helps
