According to Fleming’s left-hand rule, stretch the thumb, forefinger and middle finger of your left hand such that they are mutually perpendicular. If the first finger points in the direction of magnetic field and the second finger in the direction of current, then the thumb will point in the direction of motion or the force acting on the conductor.

The uniform magnetic field is represented by parallel, equidistant lines of equal length as shown in Figure.
The magnetic field lines have been shown in Figure given below. As per right-hand rule, we find that inside the loop, the magnetic field lines are directed perpendicular to the plane of paper in the inward direction. Outside the loop magnetic field lines are directed out of the plane of paper. For mRead more

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. For more answers visit to website: https://www.tiwariacademy.com/ncert-solutions/class-10/science/chapter-13/

Properties of magnetic lines of force (also known as magnetic field lines) are listed below: • Outside the magnet, the magnetic field lines are directed from N-pole of magnet towards S-pole. However, inside a magnet the field lines are directed from S-pole to N-pole. Thus magnetic field lines form aRead more
Properties of magnetic lines of force (also known as magnetic field lines) are listed below:
• Outside the magnet, the magnetic field lines are directed from N-pole of magnet towards S-pole. However, inside a magnet the field lines are directed from S-pole to N-pole. Thus magnetic field lines form a close loop.
• The magnetic field line at any point points in the direction of magnetic field at that point.
• The relative strength of magnetic fields is given by degree of closeness of the field lines. The magnetic field is strong in the region where the field lines are crowded.
• No two magnetic field lines can ever intersect with each other.
Magnetic compass needle and bar magnet both have magnetic field. When they brought near to each other, these magnetic fields interact each other giving deflection in needle. For more answers visit to website: https://www.tiwariacademy.com/ncert-solutions/class-10/science/chapter-13/
