Magnetic field is made up of magnetic lines.
A Magnetic Force
the magnetic keepers are made up of insulators. generally wood
no. Eris does not have a magnetic field
Magnetic fields are bascially lines of force caused by magnetic poles. It is invisible, but you can track how the field lines are formed doing a small experiment. Spread some iron fillings on a tray. Then bring a magnet up close to the iron fillings but not too close. You can observe that the iron fillings move into the field lines of the magnet that you brought up close. That's a miniature of a magnetic field. The earth's magnetic field is much bigger.
Magnetic field is made up of magnetic lines.
The earth's magnetic field is caused by convection currents in our core. The core is made out of iron, which is a magnetic metal.
iron
The Outer Core has magnetic field and it is made out of iron and nickel
It is made by the movement of the earths core and magma field
No, a magnetic field is induced by moving electric charges. If a ferrous material (one containing iron) is placed in a magnetic field, the individual magnetic dipoles can be aligned in accordance with the magnetic field. Since the molten iron in the earth's core carries charges, a magnetic field is induced around the earth (with field lines coming OUT of the south pole and into the north). This magnetic field can align magnetic dipoles just as any man-made electromagnet can.
Magnetic fields are made up by a moving electric charge within which the force of magnetism acts:)
The magnetic field collapses to zero, then builds up again for the current in the opposite direction.
It is made by the movement of the earths core
The optical microscope uses a magnetic field to magnify images up to 1,000.000
A Magnetic Force
Have you ever seen a magnet? Did you see the field? There you go. While you can't see the field itself directly, you can see the effects of the field if you use iron filings or something like that; they'll line up with the magnetic field lines
