Answer 1

If magnetic field lines intersect each other, then at the intersection point there will be two directions of the same field which is not possible. Hence the field lines do not cross or intersect each other.

Why two Magnetic field lines never intersects each other?When an electric current is passed through a wire, it is true that a magnetic field is produced around it. ... The magnetic field produced by an electric iron connecting cable is very weak and is not enough to attract nearby objectsHow can we trace the magnetic field lines of bar magnet?importing numpy as np

import numpy as np

  

  

# creating first matrix

A = np.array([[1, 2], [3, 4]])

  

# creating second matrix

B = np.array([[4, 5], [6, 7]])

  

print("Printing elements of first matrix")

print(A)

print("Printing elements of second matrix")

print(B)

  

# adding two matrix

print("Addition of two matrix")

print(np.add(A, B))

Suppose we have two matrices A and B. A = [[1,2],[3,4]] B = [[4,5],[6,7]] then we get A+B = [[5,7],[9,11]] A-B = [[-3,-3],[-3,-3]]bar magnet (or any magnet) will have a north pole and a south pole. The magnetic field lines will start from the north pole and end at the south pole. Since iron is a metal that is magnetic in nature, we can use iron filings or a magnetic compass needle to trace the magnetic field lines of the bar magnet.Printing elements of first matrix [[1 2] [3 4]] Printing elements of second matrix [[4 5] [6 7]] Addition of two matrix [[ 5 7] [ 9 11]]
