magnetic field is a quantity that has both direction and magnitude. pick out the incorrect statement (a) The magnetic field lines emerge from north pole and merge at the south pole. (b) Inside the magnet, the direction of field lines is from its south pole to its north pole. (c) Inside the magnet, the direction of field lines is from its north pole to its south pole. (d) No two field lines intersect each other and the field is strongest where the field lines are crowded.
Answers
Explanation:
Magnetic field is a quantity that has both direction and magnitude. The direction of the magnetic field is taken to be the direction in which a north pole of the compass needle moves inside it. Therefore it is taken by convention that the field lines emerge from north pole and merge at the south pole. Inside the magnet, the direction of field lines is from its south pole to its north pole. Thus the magnetic field lines are closed curves.
The relative strength of the magnetic field is shown by the degree of closeness of the field lines. The field is stronger, that is, the force acting on the pole of another magnet placed is greater where the field lines are crowded.
No two field-lines are found to cross each other. If they did, it would mean that at the point of intersection, the compass needle would point towards two directions, which is not possible.
Answer:
The correct answer of this question is No two field lines intersect each other and the field is strongest where the field lines are crowded.
Explanation:
Given - Magnetic field is a quantity which has both direction and magnitude.
To Find - pick out the incorrect statement .
The incorrect statement is there are no field lines that intersect one other. If they did, the compass needle would point in two directions at the point of junction, which is not feasible. A magnetic field has both a direction and a magnitude. The magnetic field's direction is assumed to be the direction in which a compass needle's north pole moves within it. As a result, it is assumed that the field lines arise from the north pole and combine at the south pole. The direction of field lines inside the magnet is from south pole to north pole.
