Is iron has to stick to the magnet.
Magnets have a magnetic field about them. This field can act on objects without the magnet coming in contact with the object.
Its magnetic field and its color.
Surrounding a magnet with a magnetic shell can allow the magnetic field to move farther away from its source.
No. Earth's magnetic field does not affect its axis of rotation.

the magnetic field gets stronger with increasing distance from the wire
distance is the only insulator
No. Earth's magnetic field only affects earth, not other planets.
it increases th magnetic field
by bring two magnets near we can make magnetic field for some distance.
Electricity is created by a rotating magnetic field captured by a coil. The flow of electrons creates a magnetic field.
The earth's magnetic field acts upon the magnetic material of the compass needle, causing it to align to the field. Thus, the compass appears to point North, which is "magnetic north". Magnetic north and "true north" are about 300 miles apart.
