Why can't the Earth's magnetic field go bazooka!
It's made of iron and it's got poles...

Flares are bursts of energy and matter that are emitted from the surface of a star. They are caused by magnetic reconnection, a process in which the magnetic fields within a star's atmosphere realign and release a large amount of energy. Since only stars have magnetic fields, flares can only occur on stars.
Flares and solar prominences are both solar phenomena that occur on the surface of stars. However, flares are sudden, explosive releases of energy, while solar prominences are more gradual eruptions of material from the star's atmosphere. Flares are also much more energetic and can release up to 10 million times more energy than solar prominences.
Yes, flares can have a variety of effects on Earth, some of which can be harmful. The most common effect is an increase in the intensity of the aurora (also known as the Northern and Southern Lights) due to the charged particles from the flare interacting with Earth's magnetic field. However, more powerful flares can also disrupt satellite communications and even cause power outages on Earth.
Not all stars have flares, but they are more commonly observed on younger, more active stars. This is because younger stars have stronger magnetic fields and are still in the process of forming, resulting in more frequent and powerful flares. As stars age, their magnetic fields weaken and flares become less frequent.
Flares can occur on a wide range of stars, from small, cool stars known as red dwarfs to massive, hot stars. However, they are most commonly observed on stars that are similar in size and temperature to our Sun. These stars, known as main sequence stars, have a stable core and active outer layers, making them more prone to flares.
