Answer:
What is meant by magnetic field ?
Ans:a region around a magnetic material or a moving electric charge within which the force of magnetism acts.
How is the direction of magnetic field at a point determined ?
Ans:The direction of a magnetic field at a point is determined by placing a small compass needle. The N - pole of compass indicates the direction of magnetic field at that point.
What is Sl unit of magnetic field ?
Ans:The tesla (symbol: T) is a derived unit of the magnetic induction (also, magnetic flux density) in the International System of Units. One tesla is equal to one weber per square metre.
What is the direction of magnetic field lines inside a bar magnet
The lines of magnetic field from a bar magnet form closed lines. By convention, the field direction is taken to be outward from the North pole and in to the South pole of the magnet.
Define a magnetic field line ?
Ans:A magnetic field is a vector field that describes the magnetic influence on moving electric charges, electric currents, and magnetic materials. A charge that is moving in a magnetic field experiences a force perpendicular to its own velocity and to the magnetic field.
What are magnetic field lines
Ans:Same question
What is the direction of magnetic field lines outside a bar magnet
Ans:The lines of magnetic field from a bar magnet form closed lines. By convention, the field direction is taken to be outward from the North pole and in to the South pole of the magnet. Permanent magnets can be made from ferromagnetic materials.
What does crowding of magnetic field lines indicate?
Ans:The crowding of magnetic field lines indicate the strong magnetic field. The crowding of magnetic field lines indicate a strong magnetic field around the magnet.
What does the degree of closeness of magnetic field lines near the poles signify
Ans:The degree of closeness of magnetic field lines near the poles signifies crowding of magnetic field lines which indicates that magnetic field in that region is strong.
At what place of the magnet are the magnetic field lines denser
Ans:The magnetic field lines are densest at the center and least dense between the two poles just outside the bar magnet. The magnetic field is strongest at the center and weakest between the two poles just outside the bar magnet.
The space around a magnet or current carrying conductor within which its influence can be
Ans:A magnetic field is generated when electric charge carriers such as electrons move through space or within an electrical conductor.
