Magnetism

The fatness of a hysteresis curve in a sample can be due to factors like impurities in the material, sample geometry, and microstructural features causing domain movement with different energy barriers. These factors can lead to a wider range of magnetic responses within the sample, resulting in a broader hysteresis curve.

The compass needle will turn until it's perpendicular to the wire, provided the current

in the wire is enough to generate a magnetic field around the wire that's strong enough

to swamp out the effects of the Earth's magnetic field.

(That doesn't take much current.)

It depends on what you make them out of. If the farrier has made them out of either iron or steel, then yes, but if they are soft like the plastic variety they can do, then obviously not. But there are lots of different varieties that do all sorts of jobs. I'd ask a farrier for more information.

Electric charge produces an electric field by just sitting there.

It doesn't have to move.

If it moves, it produces a magnetic field. It doesn't matter how

the motion would be described.

The two poles that attract are the north whit north or south whit south

No, coir rope will not give a north-south direction if suspended freely. Coir rope does not possess magnetic properties to align itself with the Earth's magnetic field to indicate north-south direction. It requires a magnetic compass for determining directions.

Functional magnetism refers to the use of magnetic resonance imaging (MRI) techniques to measure brain activity by detecting changes in blood flow. This method enables researchers to study brain function and connectivity in response to various tasks or stimuli.

Hitting a magnet with a hammer can disrupt its alignment of magnetic domains, potentially weakening its magnetic field. However, it will not create a new magnetic field.

Ampere's circuital law is typically used to determine the magnetic field around symmetrically arranged current-carrying conductors or solenoids where the symmetry simplifies the calculation. On the other hand, the Biot-Savart law is employed for more general cases where the magnetic field needs to be calculated at any point in space due to a general current distribution. Ultimately, the choice between the two depends on the complexity of the current configuration and the ease of application of each method.

No, magnets do not turn into flies. Magnets are objects that produce a magnetic field while flies are insects belonging to the order Diptera. They are completely different entities with no relation to each other.

Inside the hollow cylindrical electromagnet ("solenoid"), the magnetic field lines

are straight, parallel to each other, and parallel to the axis of the cylinder. They get

more complicated at the ends, but the above statement is good for a solenoid of

infinite length, which has no ends, and is a good approximation in the center of a

real one.

Yes, a magnet can be removed from a TV by carefully sliding it off without causing any damage to the screen or internal components. It's important to exercise caution to avoid causing any interference with the TV's electronic functions.

A common metal used to make the dial of a watch is soft iron, as it helps to minimize the magnetic effect on the movement of the watch. Soft iron is known for its ability to attract and channel magnetic fields, thereby protecting the delicate internal components of the watch from being affected by external magnetic forces.

A north arrow compass is a graphic element used on maps and diagrams to indicate the orientation of the map in relation to the cardinal directions. It typically points towards the north direction, helping users navigate and understand the map more easily. It is essential for ensuring proper alignment and interpretation of geographic information.

Magnets cannot directly cause centrifugal force. Centrifugal force is an outward force experienced in a rotating reference frame, while magnets produce magnetic force due to the alignment of magnetic moments within the material. These are two different phenomena.

Yes a central magnet rotating with an array of magnetic material surrounding it spun at the relative speed so as not to defeat the magnetic field would create a centrifugal arrangement if that is the query.

An electromagnet - is essentially a metal 'core' encased in wire. When power is applied to the wire, the core becomes magnetic - when the power is turned off, the magnetism is lost. Think along the lines of a crane in a scrap-yard. The crane has an electromagnet attached to its lifting arm. The operator switches on the magnet to lift a load of scrap metal, and switches it off to drop the load.

Magnetism relates to electricity because they both have to do with moving charge.

Also if you have a magnet you can produce a current through induction and if you have a current, there is a magnetic field surrounding the current. So magnetism and electricity are somewhat intertwined.

No, magnetic field lines close together indicate a stronger magnetic field, while magnetic field lines farther apart indicate a weaker magnetic field. The density of field lines represents the strength of the magnetic field in that region.

Yes, magnetic field lines form closed loops that are continuous. They always start from the north pole of a magnet, loop around the magnet, and return to the south pole.

The strongest magnetic area of a bar magnet is the sides.

CCA stands for Chromated Copper Arsenate, which is a type of treatment used to protect utility poles from decay, insects, and other environmental factors. The treatment involves applying a mix of copper, chromium, and arsenic salts under pressure to extend the lifespan of the poles.

The movement of the South Magnetic Pole is mainly due to changes in the Earth's magnetic field caused by the flow of molten iron in the outer core. These changes can be influenced by various factors, such as shifts in the distribution of mass within the Earth, the Sun's activity, and interactions with other magnetic fields.

I have constructed several using a bar magnet attached to a shaft at it's center point, so it is balanced on the shaft. Wind two coils around cylindrical steel cores. Construct a frame to support the shaft with bar magnet, and the two coils. The shaft needs to be supported so that it spins freely, and the coils need to be mounted so they both align simultaneously with the opposite poles of the bar magnet - they are 180 degrees from one another with respect to the shaft and bar magnet, and the steel rods that make up the cores of the coil are in alignment with the bar magnet. A wire end of one of the coils is connected to one end of the other coil so the coils wind in the same direction as if one coil was a continuation of the other, interrupted in the middle by the shaft and bar magnet. The opposite ends of the coils complete a circuit through an electrical load. If you spin the shaft, you should be able to read an a.c. (alternating current) voltage with a meter, across the two ends of the conductors. The more turns on each coil produces higher voltage. If you don't read anything, try swapping ends with one of the coils.

You can use LEDs at the leads and if you have enough voltage, you can light the LEDs as well as convert the a.c. voltage to d.c. voltage.

Generally speaking yes, but for the big magnets, maybe because some areas of the magnet may suffered from more shock than other areas and so the poles may have been disrupted.
