What part of the magnetic field is strongest and what part is the weakest?
The magnetic field is strongest at the poles of a magnet, where the magnetic field lines are most concentrated and closely packed. The magnetic field is weakest in the areas between the poles, known as the equator of the magnet.
What is the area of strong magnetic activity that can be seen on the sun's Photosphere?
The area of strong magnetic activity on the sun's photosphere is characterized by sunspots. These dark spots are cooler regions caused by intense magnetic fields that inhibit convection. Sunspots often occur in groups and can vary in size and lifespan. Their presence is indicative of solar activity and is linked to phenomena such as solar flares and coronal mass ejections.
A dark area of gas on the suns surface that is cooler than surrounding gases?
The dark area is known as a sunspot on the Sun's surface. Sunspots appear darker because they are cooler than their surroundings. They are caused by strong magnetic activity that inhibits convection and reduces temperature.
How does the sun get sunspots?
Sunspots are cooler regions of the Sun's surface (they are still really bright, they just look dark compared to the surrounding Sun) they are caused by what are basically magnetic field "tangles" stopping the convection that brings heat to the solar surface.
An area seen as a dark spot on the photosphere of the sun?
The darkest part, where the magnetic field is approximately vertical to the sun's surface is called the Umbra.
What is a dark area on the sun that is caused by magnetic storms?
Sunspot. See related question
What is an area on the sun cooler than any other area on the sun called?
A cool, dark area on the sun's surface is called a sunspot. Sunspots are areas of reduced temperature that appear dark against the brighter background of the surrounding solar surface because they are regions of concentrated magnetic field flux inhibiting convective flow.
Dark parts on the sun are?
Dark spots on the sun that are visible with the naked eye at sunrise/sunset are sunspots, which are cold areas caused by the sun's magnetic field.
Can astronomers learn the magnetic field of a star?
Light that comes from the sun is polarized by these magnetic fields. A meter can determine the different directions of the light and detect interference. This interference is known as a magnetic field.
What are the two parts of a sunspot?
The two parts of a sunspot are the dark central region called the umbra and the lighter surrounding region called the penumbra. The umbra is cooler than the surrounding regions and is where the magnetic field is most intense.
Why do the amount of sunspots change over time?
sunspot: A spot or patch appearing from time to time on the sun's surface, appearing dark by contrast with its surroundingThey appear because of strong magnetic forces on the sun. Our magnetic forces are changing on earth too.
What is a dark area of the sun that is cooler than the surrounding area?
A dark area on the sun that is cooler than its surrounding area is called a sunspot. Sunspots are temporary phenomena that appear as darker regions on the sun's surface due to magnetic activity.
