Question
The magnetic field produced in a straight conducting wire on passing a current through it is
- In the direction of current
- In the direction opposite to the current
- In the form of concentric circles around the wire
- The direction parallel to the wire
Hint:
The magnetic field produced in a straight conducting wire on passing a current through it is in the form of concentric circles around the wire.
The correct answer is: In the form of concentric circles around the wire
- When current flows through a straight conducting wire, a circular magnetic field forms around the wire.
- The strength of the magnetic field depends on the frequency of the electric current.
- B=μoI/2r provides the magnitude of the magnetic field produced at distance r.
