What produces magnetic field?
Magnetic fields are produced by moving electric charges and the intrinsic magnetic moments of elementary particles associated with a fundamental quantum property, their spin.
Which type of magnetic activity the Sun produces?
Surface activity Starspots are regions of intense magnetic activity on the surface of a star. (On the Sun they are termed sunspots.)
Do Suns have magnetic fields?
The Sun is a magnetic star. As these magnetic fields emerge through the Sun’s visible surface (the photosphere), they form sunspots and other active regions and create complex and dynamic plasma structures in the Sun’s upper atmosphere (corona).
What are the major sources of electromagnetic fields?
They are generated by natural phenomena like the Earth’s magnetic field but also by human activities, mainly through the use of electricity. Mobile phones, power lines and computer screens are examples of equipment that generates electromagnetic fields.
What is magnetic field quizlet?
A magnetic field is a region where. magnetic materials and wires carrying currents experience a force acting on them. In field diagrams the field lines always point from the. north pole of the magnet to the south pole.
What are magnetic field lines quizlet?
Magnetic field line is an imaginary line such that tangent to it at any point gives the direction of magnetic field at that point in space. The magnetic field lines are closed curves. Only $47.88/year. Direction of magnetic field.
How does the sun’s magnetic field create sunspots?
Sunspots are caused by disturbances in the Sun’s magnetic field welling up to the photosphere, the Sun’s visible “surface”. The powerful magnetic fields in the vicinity of sunspots produce active regions on the Sun, which in turn frequently spawn disturbances such as solar flares and coronal mass ejections (CMEs).
How the Earth creates a magnetic field?
Scientists know that today the Earth’s magnetic field is powered by the solidification of the planet’s liquid iron core. The cooling and crystallization of the core stirs up the surrounding liquid iron, creating powerful electric currents that generate a magnetic field stretching far out into space.
How does the magnetic field of the Sun work?
The sun’s magnetic field drives changes on its surface and beyond. Electric currents inside the sun generate a magnetic field that spreads throughout the solar system. The field causes activity at the surface of the sun, surging and ebbing in a regular cycle.
Sunspots are places where very intense magnetic lines of force break through the Sun’s surface. The sunspot cycle results from the recycling of magnetic fields by the flow of material in the interior . The prominences seen floating above the surface of the Sun are supported, and threaded through, with magnetic fields.
How are the prominences of the Sun formed?
The prominences seen floating above the surface of the Sun are supported, and threaded through, with magnetic fields. The streamers and loops seen in the corona are shaped by magnetic fields. Magnetic fields are at the root of virtually all of the features we see on and above the Sun.
How does the magnetic dynamo work on the Sun?
The Sun’s meridional flow – the flow of material along meridian lines from the equator toward the poles at the surface and from the poles to the equator below the surface- must also play an important role in the Sun’s magnetic dynamo. At the surface this flow is a slow 20 m/s (40 mph) but the return flow toward the equator inside
