Question

22. List the factors on which the magnetic field produced by a current carrying straight conductor
depends. State the rule which gives the direction of its magnetic field. Draw the pattern of magnetic
field lines due to a straight current carrying conductor.​

Answer 1

The factors on which the magnetic field of a current carrying straight conductor depends are:-

1. Length of the wire

2. Thickness of the wire

3. Material used to make wire

The Right Hand Thumb rule gives us the direction of magnetic field

Here's the picture of magnetic field in a straight current carrying conductor
