Draw a diagram to show the magnetic field around a straight conductor? B) what factors
does the magnetic field due to a current carrying conductor depends on?
Answers
Answer:
here is ur diagram mate ....
Answer:
When electric current flows through a conductor, an induced EMF is created which in turn creates a magnetic field around it. The magnetic field lines form concentric circles around the conductor. The direction of the magnetic field is perpendicular to the wire and is in the direction of wrapped fingers of the right hand holding the conductor and the thumb pointing upwards indicates the direction of the current.
A magnetic field implies the existence of poles and the polarity of a current carrying conductor is north-south when the current flows in the anti-clockwise direction. When magnetic compass with the north end is brought closer to the 1st end of the conductor, the needle deflects towards the west, that is away from the conductor because the magnetic compass that is pointing in the direction of the earth's magnetic field, i.e. north- south direction repels with the north pole of current carrying conductor. Like poles repel each other.
Explanation:
Magnetic field due to a current-carrying conductor depends on the current in the conductor and distance of the point from the conductor. The direction of the magnetic field is perpendicular to the wire.
