Question

Two bar magnet are kept side by side as shown in figure:

Draw the magnetic field lines between poles A and B. Our of the two points P and Q SA shown in figure, at which point the magnetic field strength will be more and why ?
Answer in about 40-60 words​

Answer 1

Answer:

Point P

Explanation:

We have learnt that magnetic lines of force are strongest towards the pole.

In lower classes, we have seen in the diagram of magnetic field lines that these are imaginary lines that are elliptical in shape. But this is the case for magnetic field in one magnet.

But in this case, north Pole of magnet A and South Pole of magnet B attract each other strongly. The magnetic lines of force will be linear and not elliptical.

Answer 2

Answer:

The magnetic field is strongest at the pole because there is an ample amount of field line assembles.

Explanation:

A magnetic field is a magnetic field generated by a moving magnet or electric charge. A magnetic field is an area around a magnetic material or transfers charge on which a magnetic force acts. The magnetic force is represented by the lines of magnetic force. This is a visual tool used to visualize the direction and strength of the magnetic field. The

magnetic force lines can be drawn with the needle of the compass. The compass needle should be placed on a piece of paper near the magnet. Check the direction the compass needle is pointing and mark the direction. Move the compass needle to another position to mark the direction. When you connect the points, the magnetic force lines are displayed.

properties of magnetic field lines:

• The tangents drawn to the lines of magnetic force indicate the direction of the magnetic field.  
• The proximity or density of the field lines is directly proportional to the electric field strength.
• The lines of magnetic force appear to occur or start at the North Pole and merge or end at the South Pole. Inside the magnet, the direction of the magnetic force lines is from the South Pole to the North Pole.
• The lines of magnetic force do not intersect.
• The lines of magnetic force form a closed loop.

• The field line has both direction and size at every point in the field. Therefore, the lines of magnetic force are represented by vectors.
• They indicate the direction of the magnetic field.  

• The magnetic field is stronger at the poles because the field lines are denser near the poles.
