Question

which describes the magnetic field that forms when a wire carries an electric current? a. It is in a line perpendicular to the wire. b. It is in a line parallel with the wire. c. It is in a cylinder around the wire. d. It is in a cylinder across the wire.

Answer 1

C.  the magnetic field is shaped like a cylinder through which the wire is positioned along the axis of symmetry.

Answer 2

Option (c)

Step-by-step explanation:

According to the Maxwell's right hand rule, If we hold a current carrying conductor in our right hand, such that the thumb indicates the direction of current flowing in the conductor then the curling of fingers gives the direction of magnetic field around the conductor.

So, the magnetic field around the conductor is in cylindrical form around the wire.
