The dark spots on the surface of the sun are sunspots. They are caused by intense magnetic activity which stops convection and causes a relatively cool spot.

Electromagnetic waves are called EM waves because they are composed of oscillating electric and magnetic fields. These fields propagate through space, carrying energy with them. The combination of electric and magnetic fields gives rise to the term "electromagnetic."
Magnets should be stored in a cool, dry place away from heat and strong magnetic fields to maintain their strength and prevent them from losing their magnetic properties over time.
No, a black surface will absorb more heat from its surroundings and radiate it back out more slowly compared to a shiny surface. This means that a shiny surface will typically cool faster than a black surface.
Minerals in rocks that cool in the presence of Earth's magnetic field can become magnetized and align with the magnetic field. This phenomenon is known as paleomagnetism, and it provides valuable information about the Earth's magnetic history and the movement of tectonic plates.

Magnetic fields that dot the surface of the sun are known as sunspots. Although they are hardly cool in temperature, they are much colder than surrounding areas, which causes them to be visible as darkened spots.

Yes, you can. It's a base of modern low temperature physics.
A place which is fire proof, shockproof, cool, dry and surrounded by no strong magnetic fields

Sunspots are caused by very strong, very localized magnetic fields in the photosphere of the sun. These magnetic fields inhibit convection currents within the solar matter, thereby preventing hotter plasma from reaching the visible region of the photosphere. The resulting effect causes a local region of the sun's surface to cool, and this cooler area appears darker compared to the surrounding areas.

Magnetic fields are stronger when cooled down. This is because the atoms that make up the magnetic material aren't moving as fast as a heated magnet's atoms. This means that the magnetic domains are less likely to move out of place and mess up the magnetic field.

These are called sunspots. These are the cooler darker areas on the sun.They range in size from 800 to 80000 km in diameter. They have very strong magnetic fields that can affect radio communications on earth. They follow an eleven year cycle called the sunspot cycle.
Iron is a key element in the Earth's core and its presence helps create the planet's magnetic field. When iron-rich materials heat up and cool down, they align in the direction of the Earth's magnetic field, creating a magnetic field of their own. This process is known as the geodynamo theory and is responsible for generating the Earth's magnetic field.
