Your question is very badly worded, as magnetism is a name of several related phenomena. It is like saying "how fast does love travel".
That said, I think you are asking how fast do the effects of magnetism travel, and that is the speed of light. For example, if you have a magnetic dipole at the origin with its dipole field everywhere in space (it has sat there stationary for eons), if you rotate it quickly. A point a distance d away, will not sense this based on the magnetic field (indeed, in no way could he sense this), until a time d/c has passed.

What is transfer of energy through space?
An electromagnetic wave is a oscillation through 2 fields, electrical and magnetic fields of the space the wave is travelling through. These oscillations are at right angles to each other. Electromagnetic waves are carried by miniscule particles of energy called photons, Light itself is one of the forms of electromagnetic waves and all EM waves travel at the speed of light 3x10^8 ms or 300 000 000 metres per second. Photons have 0 mass. Nothing with mass can truly have a higher velocity then the speed of light or EM radiation. As they are carried by photons they need no medium to travel through and can therefore travel through space/a vacuum.
Why is the location of the magnetic poles important to the survival of many species of animals?
The Earth's magnetic field protects the biosphere from harmful radiation from the sun: particularly charged particles. These the magnetic field forces to turn and travel along the magnetic lines of force where they do at last penetrate the Earth's atmosphere at the magnetic poles. This is the source of the Northern Lights. These locations are therefore locales of high harmful radiation. The fact that they are are currently in high north (and south) means that there isn't too much life there to get harmed by it. If the north magnetic pole were to be in the Amazon Rain Forest we would see a large area where life was adversely affected by the radiation.
Which form of energy does not require matter for traveling through space?
Electromagnetic radiation. Energy can also be transmitted by electric fields, by magnetic fields, and by gravitation.Electromagnetic radiation.

Which force field can accelerate an electron but never change its speed?
I would say a magnetic field. When an electron enters a magnetic field that is oriented perpendicular to its path of travel it causes the electron to loop in a circle. While the speed stays the same the velocity is constantly changing due to the circular motion. Hence same speed but undergoing an acceleration.
Ions Trapped in the Earth's magnetic field give rise to?
ultraviolet radiation
How long does it take for a microwave radar signal to travel from Earth to the Moon and back?
Approximately 2.5 secs. A 'microwave' is an electro-magnetic radiation, in the same manner as light, and uv. radiation. Being an electro-magnetic radiation it will travel at the speed of light, which is 'c' = 3.8 x 10^8 m/s
Wwhat speed do gamma rays travel at?
Like all forms of light (ie, electro-magnetic radiation), gamma rays in a vacuum travel at exactly 299,792,458 meters per second.
Why is radiation called electromagnetic?
Radiation does not have to travel through a medium and travels in the form of changing magnetic and electrical fields.
What do not travel at the speed of light?
Nothing except electromagnetic radiation do.
Do other forms of radiation from the electromagnetic spectrum also travel at the speed of light?
Yes, all travel at the speed of light.
How can you calculate speed of radar?
Radar emissions are electromagnetic radiation that travel at the speed of light.
What do all types electromagnetic radiation have in common?
They travel at the speed of light (c = 3*108 m/s)
At what speed does all EM radiation travel at?
In a vacuum, 3x10^8 ms^-1. Basically the speed of light, it is EM radiation afterall.
Does radio waves always travel the speed of light?
Radio waves, like light, is a form of electromagnetic radiation. Other types of electromagnetic radiation include X-rays, infrared radiation, and gamma rays. All electromagnetic radiation travel at the speed of light.
Does light in air travel faster than radiation from microwave oven?
No, they travel at the same speed.
Electromagnetic radiation and sound waves travel at the same speed?
Yes.
How does the speed of visible light compare with the speed of gamma ray?
Gamma radiation is the fastest, as it is light. speed of gamma radiation = c (light speed) speed of beta radiation < c ( below light speed ) speed of alpha radiation < c/10 ( far below light speed )
