Question

Answer 1

Answer:

magnetic field lines: the magnetic field is an abstract entity that describes the influence of magnetic forces in a region. Magnetic field lines are a visual tool used to represent magnetic fields. They describe the direction of the magnetic force on a north monopole at any given position. Because monopolies are not found to exist in nature, we also discuss alternate means to describe the field lines in the sections below.

When an electric current flows through a conductor, an induced electromotive force is generated and a magnetic field is generated around it. The lines of magnetic force form concentric circles around the conductor. The direction of the magnetic field is perpendicular to the wire, pointing towards the wrapped finger of the right hand holding the conductor, and the upward thumb pointing in the direction of the current.

The magnetic field means the existence of a pole, and when the current flows counterclockwise, the polarity of the current-carrying conductor becomes north-south. When the magnetic compass is brought closer to the northern end of the conductor, the needle is deflected west because the magnetic compass that points in the direction of the earth's magnetic field collides. That is, it moves away from the conductor. The North Pol is  in the north-south direction of the current-carrying conductor. They repel each other like poles. This is the basic principle of magnetism.

Answer 2

The diagram is given below.

Diagram indicating the field lines of a magnetic field around a straight conducting wire:

Magnetic field lines -

• The influence of magnetic forces on a location is described by the magnetic field, an abstract concept.
• Magnetic fields can be represented visually using magnetic field lines.
• In each case, they specify the direction of the magnetic force acting on a north monopole.
• An induced electromotive force and a magnetic field are produced when an electric current runs through a conductor.
• Around the conductor, the magnetic force lines create concentric circles.
• The right hand holding the conductor has its finger wrapped, and the thumb is pointing upward in the direction of the current.
• The magnetic field is perpendicular to the wire and points in that direction.
• The magnetic field indicates the presence of a pole, and when the current moves in the opposite direction, the conductor's polarity changes to north-south.
• The magnetic compass that points in the direction of the earth's magnetic field collides when it is brought closer to the northern end of the conductor, deflecting the needle west.
• It does this by veering away from the conductor.
• The current-carrying conductor's north-south direction is indicated by the North Pole.
• They act as poles that repel one another.

Thertefore, the diagram:-
