Magnetism

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.

The type of force in a bar magnet suspended freely is magnetic force. The magnet aligns itself with the Earth's magnetic field, resulting in a net force acting on the magnet.

The poles on a net are typically known as "posts" or "supports." They provide the structure and stability needed to keep the net in place.

The force acting is called magnetism. When a paper clip is attracted to a magnet, it is due to the magnetic field produced by the magnet interacting with the magnetic properties of the paper clip, causing them to be pulled towards each other.

No, a non-magnetic drill collar cannot be magnetized because it is specifically designed to have low magnetic permeability. This property helps reduce interference with directional drilling tools that rely on magnetic measurements to navigate the wellbore.

Magnetic hysteresis is the phenomenon where the magnetization of a material depends not only on the current magnetic field, but also its history. When the magnetic field is applied and then removed, the material retains some magnetization, showing a lag or "memory" in its response to changing magnetic fields. This results in the characteristic hysteresis loop observed in magnetic materials.

The simple answer is that it takes much less time and energy to store them in the attracting potions.

If you tried to store magnets in non attracting positions they will attempt to push themselves away from each other or align them self to the attracting positions of the other magnets.

If forced togeater in non attracting positions over time they could become demagnetized or the weaker ones will realign to the polarity of the strongest magnetic force.

No, bitumen is not magnetic as it does not contain any magnetic properties. It is a natural substance derived from crude oil and is primarily composed of hydrocarbons.

Durdle Door is located on the south coast of England, facing south-southwest.

Yes, steel can be magnetized and will attract to a south pole magnet due to its ferromagnetic properties. When a steel material is in close proximity to a magnet, the magnetic domains within the steel align with the external magnetic field, leading to attraction between the two.

Yes, a magnet can pick up steel BBs because steel contains iron, which is a magnetic material. The magnet will attract the steel BBs due to their magnetic properties.

The pull of a magnet is usually stronger than its push. This is because the magnetic force is generated by the alignment of magnetized atoms within the material, resulting in a stronger attraction (pull) between magnets compared to the repulsion (push) force.

Yes, nitinol is a type of shape memory alloy made from nickel and titanium. It is not inherently magnetic but its properties may change depending on the specific composition and processing methods used to create the alloy.

Yes, lodestones are naturally magnetized pieces of the mineral magnetite that act as natural magnets with north and south poles.
