How will magnetic minerals align in a rock if earth has no magnetic field?
Assuming there is no Earth magnetic field, and no other significant magnetic fields, they will not allign in any preferred direction.
Does magnetic paint on a wall cause problems for computers in the room?
No, magnetic paint just allows magnets to stick to the paint, it is not magnetic itself. Even if it was, it would be much too weak to cause any damage.
How could earths magnetic field magnetize an iron bar over years?
I see where you're going, and it is feasible, but any magnetic charges that develop in it would be veryextremely minute (meaning very little). But to answer your question, Earth can magnetize an iron bar because the poles in iron are scattered in different directions, and as it's just laying there, they naturally align with Earth's magnetic field. It's hard to explain, because magnetism is such an abstract force, but all I can say is that it naturally happens.
Which force opposes gravity?
Any force with an upward vertical component does.
Are all magnets man-made?
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.
Does any of the rides at dreamworld use friction?
None of the rides at Dream World run with friction. The rides use a box style brake similar to B&M.
What force do electromagnets produce?
Electromagnets produce a magnetic force when an electric current passes through them. This force is the result of the interaction between the magnetic field generated by the current and any nearby magnetic materials or other electromagnets.
Why magnetic force not do any work?
Magnetic force does not do any work because it acts perpendicular to the direction of motion of the charged particle. Work is defined as force acting in the direction of motion, and since magnetic force acts perpendicular to the motion, it does not transfer energy to the particle in the form of work.
Can An electric current be produced by a changing magnetic force?
It's not the force. It's the changing magnetic field surrounding an electricalconductor, whether or not that conductor feels any force due to the field.
Why a stationary charge do not feel any force in magnetic field?
we know that force on a charge in magnetic field F=qvbsinx q-charge v-velocity b-strenth 0f magnetic field x-angle between the motion of chage and the magnetic field as the charge is stationary so v=0 so,F=0 so charge donot fill any force on it.
What happens when no net force acts on a loop of wire in a magnetic field?
When no net force acts on a loop of wire in a magnetic field, the loop will not experience any acceleration or movement.
How is the magnetic force like centripetal force?
If a charged particle moves in a magnetic field then Lorentz magnetic force acting will be perpendicular to its movement and so the particle will be taken along a curved path. Lorentz force will be towards the centre of the curved path. Any force facing towards the centre of the curved path is named as centre seeking or centripetal force.
What is magnetic motive force?
mmf is which sets up or tends to set up the magnetic flux in magnetic circuitNote. The term is magnetomotive force, notmagnetic motive force. For a coil, the magnetomotive force is the product of the current flowing in that coil and the number of turns, and is measured in amperes (A), although it is often spoken as 'ampere turns', to avoid any confusion with current.
What are the factors that affect the strength of magnetic force?
Factors that affect the strength of magnetic force include the distance between the magnets, the material the magnets are made of, the size and shape of the magnets, and the orientation of the magnets relative to each other. Additionally, the presence of any magnetic shielding or intervening materials can also influence the strength of the magnetic force.
What is the relationship between the direction of the magnetic field at any point and the direction of the force acting on a particle in that field?
The direction of the magnetic field at a point determines the direction of the force acting on a charged particle moving through that field. The force is perpendicular to both the magnetic field and the velocity of the particle.
True or false any material that exerts magnetic force is considered a magnet?
It is true that materials that exert magnetic forces are considered magnets. This is the case since it shows they have magnetic field lines that may have been induced or were naturally present in the materials.
Can magnetic force pass through cardboard ramp?
does magnetic forces pass through cardboard? <><><><> Very easily. Lay a paperclip on a sheet of cardboard. Place a magnet beneath the cardboard. When you move the magnet, the paperclip will also move.
