Question

Which of the following statement is incorrect regarding magnetic field produced due to a straight current carrying conductor?

Options

Choose one · Correct answer highlighted

The strength of the magnetic field will increase at a given point if we increase the magnitude of current in the conductor. The strength of the magnetic field will be more as we move ahead from the conductor for the same current. Correct The direction can be obtained from right hand thumb rule. If another current carrying conductor is placed near given conductor, it will experience a force.

Explanation

Field circles conductor, direction by right-hand rule, magnitude B=μ0I/2πr.
