Question

Identify the poles of the magnet in figure (a) and (b) shown below.

Answer 1

Hint: In this,we find out the poles of the magnet using field lines of the magnet. Field lines are used to show the direction of the field lines which are generated by the magnet. They also show the path of the magnetic force. Using these lines we can easily find the magnetic force and magnetic field to identify the poles of a magnet.

Complete answer:
So we have given the diagrams in which they show us the field lines of the magnet.
Since if we see the magnetic lines of the magnet in the figure we can easily find out the pole of the magnet.
As we know in the Magnet, magnetic field lines are emitted from the North Pole and unite at the South Pole.
(a).In this Figure, We find out the direction of the poles in the magnet. Here in this figure magnetic lines are emitting from the left side and unite on the right side of the magnet. This means from which side magnetic field lines are emitting is the North Pole and the other side in which they unite is the South Pole.

(b).In this figure also magnetic field lines are emitting from the left side and unite on the right side of the magnet. This means from which side magnetic field lines are emitting is the North Pole and the other side in which they unite is the South Pole.

Note:
To understand the magnet we know about the magnetic properties of the magnet. According to the properties of the magnet, these field lines always go to the North Pole and the South Pole. The form which these field lines emit is the North Pole and in which these field lines are united is the South Pole.If you know about these rules then you can easily solve this question.
