Want this question answered?
Maxwell's equations state that electric fields create magnetic fields, and vice versa. If you have a current, you have a magnetic field. If you have magnets, you have an electric field.
Magnetism or magnetic field is the attraction for iron , associated with electric currents as well as magnets characterized by fields of force
Magnetic field are unaffected by those materials. Magnets and electrical fields in general are only effected by other magnetic fields. 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 have the equation but its simple and straight forward. So if you want a magnetic field to extend through a thick (5mmm) cardboard or plastic 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.
The strongest man made magnets are those associated with the Large Hadron Collider. The strongest magnetic fields are produced by collaped stars.
No. The north sides of two magnets do not stick together because they have the same polarity. The north and south sides of a magnet, however, do stick together because they are on opposite poles and, pertaining to magnets, opposites attract. actually if you push two repelling magnets together so they touch they will stick, without flipping, not entirely sure why they don't repel but it seems that the magnetic fields somehow overlap, so that within the repelling field there is a small of the attracting field, i know this isn't true of the attracting side because the magnets stick together regardless, but on the repelling side when they touch they will stick
They will combine to make a single magnetic field.
It sticks
yes
Yes. They don't have actual magnets, but they do have "magnetic fields". Other planets with magnetic fields are Mercury, Jupiter, Saturn, Uranus and Neptune.
Faraday showed that a wire passing through a magnetic field will produce electricity. This is how a generator works. Many windings of wire on an armature spin in a magnetic field. This makes electricity.

Yes.
Magnets and electric motors are similar in that they both produce magnetic fields.
Yes! It should. Since the magnets, irrespective of external magnetic fields, have their own magnetic field. Vacuum or Air pressure, quality, etc also don't effect the magnetic fields of magnets. Hence, depending on Negative or Positive side of the magnets, when brought together, it will attract or repel accordingly!!
Ferro magnetic materials (those attracted to magnets) have a special arrangement of their electrons which makes them susceptible to magnetic fields. Materials without this special electron structure are not affected my magnets or electric fields in the same way.

Magnets can retain a permanent magnetic field. All atoms have a magnetic field which are randomly arranged in the object. Magnets and ferrous metals can retain or temporarily align the atomic fields, thus they are magnetic.
