The image depicts a magnetic field resulting from the interaction between a south pole and a north pole, forming the characteristic hourglass shape. Here option C is correct.
A magnetic field is created by the movement of electric charges, such as electrons. A magnet has two poles, north and south, where the magnetic field is strongest. The magnetic field lines emerge from the north pole and enter the south pole, forming a closed loop. The direction of the magnetic field is indicated by the arrows on the field lines.
The image shows a magnetic field in the shape of an hourglass, with a red bar in the center. The red bar represents a magnet, with the north pole on the top and the south pole on the bottom.
The green and black lines represent the magnetic field lines, which are curved and point from the north pole to the south pole. The field lines are closer together near the poles, indicating a stronger magnetic field, and farther apart in the middle, indicating a weaker magnetic field.
The other options are incorrect because they do not match the shape and direction of the magnetic field shown in the image. Option A and B would create a repulsive force between the two poles, resulting in a diverging field. Option D would create no magnetic field, since a copper bar is not a magnet. Here option C is correct.
