the magnifying glass must be positioned so as to focus the light from the sun on a single point (ex. kindling), causing heat and hopefully, a small fire
A magnifying glass can be used to start a fire by focusing sunlight onto a small area, such as dry leaves or paper, which can generate enough heat to ignite the material and start a fire.
A magnifying glass can be used to concentrate sunlight onto a small area, increasing the temperature and creating enough heat to ignite flammable materials like paper or dry leaves. By focusing the sunlight through the magnifying glass onto the target material, the intense heat generated can start a fire.

It can take just a few seconds to a few minutes for a fire to start using a magnifying glass, depending on the intensity of the sunlight, the flammability of the material being focused on, and the skill of the person using the magnifying glass.

If you mean 'set fire to something' then no, there is most unlikely to be enough energy in a normal light beam even when it's focussed with a magnifying glass. It does depend on the power of the light, of course. How many watts do you think it will take
A magnifying glass can be used to concentrate sunlight onto a specific spot, increasing the intensity of the light and creating heat. This can be used to start a fire, cook food, or generate electricity through a solar panel.
a glass one
A magnifying glass is typically made with a convex lens, usually made of glass or plastic. The lens is specially shaped to magnify objects when viewed through it. The handle of the magnifying glass is usually made of plastic or metal for easy handling.

A magnifying glass or a microscope.
My cousin and I used a magnifying glass to see the paper.
