What does not create a magnetic field?
A great many things do not create magnetic fields. They includerock,plastics,most living things,most gases at normal conditionsActually most living things create magnetic fields measurable and commonly called brain waves. minute but measurable
How can electromagnetic waves be produced?
Any electric charge undergoing acceleration will produce Electromagnetic waves. This is by far the most common way.If an oscillating electric field is synchronized with an oscillating magnetic field of exactly the same frequency a beam of light will be produce where the two fields are orthogonal in all dimensions.
Can the magnetism of the earth keep us on the earth like gravity?
No. The material that people and most other objects are made of is not strongly affected by magnetic fields.
What uses short bursts of a magnetic field to produce images?
the magnetic resonance imaging, also abbrieviated as: M.R.IA digital camera uses short bursts of a magnetic field to produce images. The images are then stored on a disk or other memory source within the camera. The disk can then be inserted into most computers to download the images.
Are gamma rays affected by electric and magnetic fields?
Most cosmic rays would be deflected by a magnetic field, with the degree of deflection depending upon their mass and the strength of the field. Remember that cosmic rays are largely protons or atomic nuclei and as such most of them do carry a charge and hence would feel the force or influence of electric or magnetic fields. Secondary cosmic rays are partly composed of electrically neutral particles (like neutrons) which would not feel the influence of magnetic fields and hence would not be deflected.
The ends of a magnet have the most?
they have the most powerful magnetic fields
Which planet has a magnetic shield?
All planets have magnetic fields. I believe that in most cases, this magnetic field can act as a shield.

Can magnetism pass through glass and why?
I don't think magnetism is affected by glass. Edit: Magnetic field are unaffected by glass. Magnets and electrical fields in general are only effected by other magnetic fields and materials which generate them. Think of a compass that is brought near another magnet. Magnetic fields are exponential in strength meaning that they are most strong at the surface and quickly fade with distance. Dont remember the equation but its simple and straight forward. So if you want a magnetic field to extend through a thick (5mmm) piece of glass you will need larger more powerful magnets such as rare earth or neodymium magnets. Its really about the strength of the magnet and the distance of the magnetic field. Hope that helps.
What is meant by electric and magnetic field?
A magnetic field is a area in which magnetic objects are pushed or pulled. It is caused by the alignment of parts of atoms.A field of force associated with changing electric fields , as when electric charges are in motion. Magnetic fields exert deflective forces on moving electric charges. Most magnets have magnetic fields as a result of the spinning motion of the electrons orbiting the atoms of which they are composed; electromagnets create such fields from electric current moving through coils. Large objects, such as the earth, other planets, and stars, also produce magnetic fields. See Note at magnetism.
How can electromagnetic waves be produced?

This is by far the most common way.If an oscillating electric field is synchronized with an oscillating magnetic field of exactly the same frequency a beam of light will be produce where the two fields are orthogonal in all dimensions.
Magnetic field intensity of a straight conductor?
magnetic field is a region of space where a north magnetic monopole experiences a force. The direction of the field is by definition the direction of the force on the north end of a magnet. Since most texts contain diagrams of magnetic fields they will not be reproduced here.
What would happen if Earth's Magnetic field was a hundred trillion times more powerful than it currently is?
Most life forms are not affected by magnetic fields; for example, an MRI machine - Magnetic Resonance Imaging - causes VERY intense magnetic fields, and they don't harm the people who are inside them. (It's cramped and noisy, but the magnetic field doesn't hurt them.) The effect may be different for VERY high fields; we don't know. Electronic equipment would be incinerated by its own induced voltage, and iron and nickel deposits within the Earth would vaporize.
Relationship between magnets and electricity?
The relationship between electricity and magnetism is intimate. A changing magnetic field induces electrical current in a wire, and is the basis for electrical generation. Also, an electrical current flowing through a wire creates a magnetic field, and is the basis for most motors.In general, a changing magnetic field creates an electrical field, and a changing electrical field creates a magnetic field. In fact, light is exactly this; two fields oscillating at right angles, and inducing one another through space.One of the four fundamental forces in the universe is the electromagnetic force. Not the electric or the magnetic force, but the electromagnetic force. Basically, you can't have electricity without magnetism and vice versa. That may not make electricity and magnetism exactly the same, but they are intertwined in a most intimate way.
Can the magnetism of the earth keep us on the earth like gravity?
No. The material that people and most other objects are made of is not strongly affected by magnetic fields.
What is performed by earths magnetic fields?
Its main 'function' is to block most of the ultra violet radiation from the sun. Without the magnetic field - the UV radiation would be far too high to allow life to survive here.
