The image shows a magnetic field around the poles of a magnet. identify the areas where the magnetic force is the strongest

Nearest points of North and South pole is having maximum magnetic force

Explanation:

As we know that magnetic force on an object is given by formula

here we know that

= magnetic charge or magnetic material strength

= magnetic field strength

now if magnetic field strength is more then we can say that the magnetic force will more.

Now if we see the figure the magnetic field lines are more dense and more closer to each other then it will show stronger magnetic field.

So here the positions near to the poles of magnet that is either North pole or South pole then at those positions the magnetic force will be maximum

convex lenses are thicker at the middle. rays of light that pass through the lens are brought closer together (they converge). a convex lens is a converging lens. when parallel rays of light pass through a convex lens the refracted rays converge at one point called the principal focus.
