Q614
A current carrying conductor is associated with
A.
A magnetic field
B.
An electric field
C.
An electro-magnetic field
AnswerD.
An electrostatic field
Answer: Option C
Solution
Answer: Option C
Solution:
A current carrying conductor, such as a metal wire, will produce a magnetic field around it because of the motion of charge within the wire itself. This motion produces or sets up a magnetic field around the wire in the form of concentric circles. This electromagnetic effect is described in physics by the Biot-Savart Law, an experimentally deduced inverse-square law. The effect is also described by Ampere’s Law, which is derived from the Biot-Savart Law.
