Question

Which of the following describes what occurs to the magnetic field produced by a current carrying wire when there is no electric current flowing through the wire?
A.nothing
B.the magnetic field is stronger
C.there is no magnetic field
D.the magnetic field is weaker

Answer 1

There is no magnetic field.

Answer 2

Answer:

The answer is c) there is no magnetic field

Explanation:

The magnetic field is produced when an electric current circulates through a conductive material; When the electric current stops flowing over this conductive material, the magnetic field disappears. To calculate the expression for the magnetic field that is produced by a current, the laws of Biot-Savart and the law of Ampere are used.
