WHAT happens when you run salt water through a magnetic field?
You can use a magnetic field to move salt water. Magnetohydrodynamics.
What can you use to show the magnetic field of a magnet for people to see?
Little bits of other magnet. Iron filings - the small pieces of metal will floow the magnetic field lines.
How does changing current affect the magnetic force on a wire suspended in a magnetic field?
Current passing through a wire in a magnetic field creates its own magnetic force in some direction. If you increase the current, force will be increased. If the direction of current is changed, direction of force will also be reversed. Direction of current is found by applying right hand rule.
What kind of electrical sensor does a metal detector use?
One which responds to the disruption of a magnetic field.
How do you levitate with electricity?
Create magnetic field and use polar opposite material and create levitation
What can you use to find the shape of a magnetic field?
a compass
Could you use compass in Venus to find way?
Probably not, because Venus has no significant magnetic field.
How is the earths magnetic field used for navigation?
Compasses use the magnetic field to navigate always pointing North.
WHAT happens when you run salt water through a magnetic field?
You can use a magnetic field to move salt water. Magnetohydrodynamics.
What is the invisible force around a magnet called?
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
What is magnetic line of induction?
The process by which a substance, such as iron or steel, becomes magnetized by a magnetic field. The induced magnetism is produced by the force of the field radiating from the poles of a magnet.AnswerThere is no such thing as a 'magnetic line of induction'. Induction is a process, by which a changing current induces (causes) a voltage into the same conductor or an adjacent conductor.A 'line' on the other hand, is imaginary and is simply a method of modelling a magnetic field in such a way that we can visualise its shape, rather in the same way that we use contour lines to show the shape of hills, etc.
How can you see the invisible magnetic field?
You can make magnetic field lines with a magnet. You an use a permanent magnet, or an electromagnet.
Use magnetic field in a sentence?
Magnetic compasses will become unuseful when near a magnetic field.
What organisms are able to sense earth's magnetic field and why?
Many (but not all) birds, fish,, insects, etc. have the ability to sense earth's magnetic field. They use this ability for navigation purposes, much as we use magnetic compases.
How would you use an electric field to produce a magnetic field that increases in size?
:-P
How do i use the earth's magnetic field to tell me where to go?
..get a compass?
What practical use is the Earth's magnetic field put to?
our walking
