What is a good sentence for magnetic reversal?
The sun goes through a magnetic reversal twice in every sunspot cycle.
What is The magnitude of an alternation which varies from zero is called its?
I will first answer this from an electrical viewpoint. The maximum positive excursion from zero would be the PEAK, or MAXIMUM portion of the cycle. From a magnetic point, it would be POSITIVE. The negative excursion of the electrical cycle (below zero) would be the MINIMUM. It would be NEGATIVE from a magnetic perspective.
What is the estimated time for a magnetic reversal to occur?
In the sun, the cycle corresponds with the cycle of visible sunspot numbers, and is roughly 11 years. In the Earth, the cycle of magnetic reversal appeares to be very irregular, with periods anywhere between 200,000 and 400,000 years. In both cases, the reversal is not something that happens suddenly at, say, 11:36 one morning. It happens gradually and continuously. For something to compare it to, think of a wave on the lakeshore ... Is the wave in, or is it out ? It's changing smoothly between the two extremes. Similarly, both the sun and the Earth are in the process of magnetic reversal right now.
What three factors determine the amount of energy required for an activity?
the three factors that determine the energy cycle are solar power, electricity, and heat.
Is it possible for the opposing magnetic field to be strong enough to completely stop an object from falling?
No because the magnetic field induced attracts the falling magnet, creating a force which slows down the magnet. If the magnetic field increased to a certain point where the force acting on the magnet was enough to stop the magnet from falling, gravity would act on the bob, causing the magnet to speed up again until it reaches a happy medium speed (or even a terminal speed if you will). When this happens, a changing magnetic field occurs and an induced current is formed again. This cycle repeats.
Why do solar flares and prominences occur in 11 year cycles?
They are related to changes in the Sun's magnetic field, which has a cycle of 22 years. The causes of this magnetic cycle are not known for sure.
What drives the solar magnetic cycle?
The solar magnetic cycle is driven by the magnetic flux.
Dark cooler regions appearing on the sun that has an eleven-year cycle?
Sunspots are dark cooler regions appearing on the sun that has an eleven-year cycle. They are as a result of intense magnetic activity.
Why is Nitrogen non reactive?
the nitrogen cycle requires - polarity...
How are the suns magnetic and it's activity cycle related?
The sun's rotation twists the magnetic field lines of force, causing hot spots of magnetic activity at the surface. The magnetic field slows down convection of energy produced by fusion below the surface, which causes a cooling effect(a sunspot). The magnetic field breaks down eventually and the sunspot dissipates, and convection goes up above normal in the region. Over time, magnetic field activity induces/creates other magnetic fields, decays, then those magnetic fields rebuild the old one, then they decay, and it goes on and on like that. The direction of the largest/main field reverses like a pendulum every 11 years.

How long is the Sun's Magnetic Cycle?
About 11 years - it varies. This cycle is late.
What ways can an astronomer determine when on 11 year old sunspot cycle ends and another begins?
The sunspots in each cycle are of the opposite magnetic polarity. As the number of spots declines to near zero, we can tell when the new cycle has begun when new spots of the opposite polarity are appearing while no "old cycle" spots appear. This has been a difficult transition; the sunspot number went to zero - and STAYED THERE, for nearly two years. Only since December 2009 can we really say that the Sun is becoming more active. The easiest way to track this is on the Web; visit www.spaceweather.com regularly.
What occurs in a eleven year cycle?
The cycle of sunspot activity.
