What does a circuit diagram for a scrap heap magnet looks like?
The cicuit at first is all conected when it is turned on then the person driving the machine will turn the engine off and the circuit will disconnect causeing the magnet not to keep hold of the metal.
Carlos' teacher has asked him to separate a mixture of sand and iron filings. Which of these methods would correctly separate the mixture?
the correct answer would be -( magnetic attraction of one part )
What does pole mean in magnet?
Sailboats have many "poles". The ones that I think you are referring to are the mast and the boom. The Mast is the Tall one that sticks up out of the hull. The is connected horizontally to the mast.
HOW does electricity make motion?
Electric motors work by placing the opposite poles of an electromagnet that is fixed onto a spindle or axle near to either end of a fixed magnet. This causes the moving electromagnet to spin slightly then come to a halt. If, at the correct time, the battery or other source of current feeding the electromagnet is flipped - thus reversing the polarity - it will complete another slight spin in the same direction. The repitition of this action provides the movement required to make the spindle of the motor rotate.Other answersWhat makes a motor turn is based on the fact that magnetic fields produce physical force that can move things. If you have ever played with magnets you have seen this in action as you use one magnet to attract another magnet or force it to move without touching it, depending on how you line up their poles.All magnets have a north pole and a south pole. Like poles repel each other and unlike poles attract each other.So, in a motor, electricity is used to create magnetic fields that oppose each other and cause something to move, which happens to the motor's rotating part, called the "rotor".On the rotor there are loops of wiring - called "windings" - that have an opposing magnetic field to a magnetic field produced in the housing of the motor that does not move, which is called the "stator". Its magnetic field is produced either, in the case of a very small motors, by permanent magnets or, for most other sizes of electric motor, by loops of wiring called"field windings".It is the repelling action of the opposing magnetic fields which causes the rotor to turn inside the stator.In heavy electric motors having field windings, big problems can arise from excessive heat buildup - including a high risk of the motor's windings and/or its power input cables catching on fire - if something ever prevents the rotor from turning whilst it is still being supplied with electricity. If properly-sized circuit breakers are not installed to give the motor adequate overcurrent protection, any general overloading of the motor or siezed rotor shaft bearings can easily cause such problems.For more information please click on the Related Linkbelow.Electric motors convert electrical energy to mechanical energy.Inside the cover of any electric motor there are 2 kinds of magnets:One does not move and is called the "stator". On some kinds of electric motors the stator can be a permanent magnet and on others it can be an electromagnet.The other kind of magnet is called the "rotor" because it rotates inside the stator. The rotor is always an electro-magnet and when you give it electricity, its copper coils make its metal pieces (which are in the middle of the coils) magnetic.
If a wire had a current which was continually reversing directions and hten was placed between the poles of a magnet what would happen to the force on the wire?
Draw an imaginary line between the poles of a horseshoe magnet, say horizontal. If the wire is along that line there will be no magnetic force on it because the current would be parallel /antiparallel to the magnetic field. If the wire is perpendicular to the line, say vertical, the magnetic force on the wire will be in then out. If the wire is perpendicular ,say in/out, then the magnetic force will be vertical up then down. That's what the magnetic force would be, It changes direction when the current changes direction. To actually see the effect however could be difficult because; the wire has to be part of a circuit which could cause problems giving it enough "freedom" to move. If you use household current, which changes direction every 1/120 th of a second, the wire will not have time to move very far before the force changes directions and its doubtful you will be able to see the motion. Finally even if the current changed more slowly you still need a pretty strong current (a few amps) and a pretty strong magnet to see the effect.
A magnetic pole is the part of a magnet where the magnetic effect is weakest?
Actually, a magnetic pole is the region of a magnet where the magnetic force is concentrated. It is at the poles of a magnet where the magnetic effect is strongest, not weakest.
What part of the magnet would be the best area to attract metal to?
The strongest magnetic attraction typically occurs at the poles of a magnet. These are the regions where the magnetic field is most concentrated, making them the best areas to attract metal objects.
What part of a magnet is greatest?
The poles of a magnet are the parts where its magnetic field is strongest. The north and south poles are the regions where the magnetic force is concentrated and where other magnetic materials are most affected.
Is it true that the magnetic force becomes stronger towards the centre of the magnet?
No.The part of the magnet where there is the strongest pull or attraction are called the poles of the magnet.
What part of the magnetic field is strongest and what part is the weakest?
The magnetic field is strongest at the poles of a magnet, where the magnetic field lines are most concentrated and closely packed. The magnetic field is weakest in the areas between the poles, known as the equator of the magnet.
What part of a magnet is concentrated?
The magnetic field of a magnet is concentrated at the poles. These are the points on the magnet where the magnetic force is strongest and where attraction or repulsion is most noticeable.
What part of a bar magnet has the strongest force?
The highest concentration of magnetic lines of force is at the poles of the magnet. It's that simple. Here's why. The lines of force are all "bundled together" inside the magnet, and run its length to emerge at one pole. Then the lines of force spread out to "go around" or "surround" the magnet to reach "around" to go back to the other pole. Then they concentrate at that other pole to return to the inside of the body of the magnet.

On Earth, I'd guess that those used in MRI machines would be right up there, but the fields used to steer particles in the hadron collider may be worth a check as well. I have no numbers readily available for you.
Where is the strongest and weakest part of a magnetic field?
The strongest part of a magnetic field is typically closest to the magnet or electrical current creating it, while the weakest part is farther away from the source. Magnetic field strength decreases with distance from the source due to the inverse square law.
In what part of the magnetic field are the magnetic field lines closet together?
Magnetic field lines are closest together at the poles of a magnet, where the magnetic field is strongest. This is where the magnetic force is most concentrated.
Where are the Magnetic field lines closest together?
The field is strongest on the poles of the magnet (the ends of the magnet). More specifically, the 8 corners of the magnet are where the strongest magnetic field will occur. The weakest field occurs in the center of the magnet.
Where is a bar magnet's pull strongest?
A bar magnet is strongest at its ends, or poles. This is because there is a magnetic field, or B field, that is produced by the magnet itself. The magnetic field can be represented by magnetic field lines, which enter one end of the magnet and exit the other.For instance, in a bar magnet, the magnetic field lines emerge from the north pole of the magnet and enter the magnet at the south pole. Since a magnet has two poles, it is said to be a magnetic dipole.The magnetic field lines are most closely packed together at the poles, since it is a short distance to the opposite pole of the magnet. This is why a bar magnet is most effective at short distances. Picking up a paperclip from a centimeter or two away is much easier than trying to magnetically attract a paperclip to a magnet from a distance greater than five or six centimeters.
What is magnet energy a part of?
Magnetic energy.
