Question

two small bar magnets are placed in a plane. direction of their dipole moments a d the position of magnets are as shown in the figure. the appropriate direction of net magnetic field at point P will be by which of the following arrow?​

Answer 1

Answer:

(4)

Explanation: As thr magnetic field lines emerge from North pole, its direction will be (4)

Answer 2

The direction of net magnetic field will be option (4)

Magnetic field lines-

Magnetic field lines emerge from the North pole and go into the South Pole of a bar magnet.

Head to the tail rule of vectors-

Place the tail of the first vector at the head of the second vector and draw the resultant vector from the tail of the first vector to the head of the second vector.

Explanation:

• As the first vector, we take the maroon color vector, and as the second vector, we take the black color vector.
• The resultant vector is orange in color.

According to the diagram drawn, the resultant vector is emerging from South to North.

Since we know magnetic field lines emerge from North to South, the vector is taken as opposite, to make it North to South.

Explanation to incorrect options:

(1) resultant vector not option 1 as per head to tail rule.

(2) resultant vector not option 2 as per head to tail rule.

(3) resultant vector not option 3 as per head to tail rule.

Hence, the direction of the net magnetic field will be option (4).
