Magnetism

Yes, iron chains are magnetic because iron is a ferromagnetic material. This means that it can be magnetized and is attracted to magnets.

According to Ampere's Law, the strength of the magnetic field around a long, straight wire carrying current is directly proportional to the current and inversely proportional to the distance from the wire at which it is measured. Assuming fixed distance from the wire (meaning that you're measuring in the same place), if you increase the current by 1.75/.25= 7 times, you will also increase the magnetic field by 7 times.

No, glass is not a material that is attracted to magnets. Magnets can attract materials such as iron, nickel, and cobalt, but glass does not contain these magnetic properties.

Hans Christian Oersted discovered the relationship between electricity and magnetism in 1820 when he observed that an electric current flowing through a wire caused a nearby compass needle to deflect. This observation demonstrated that an electric current produces a magnetic field.

Magnetic sweepers are commonly used in the industry to clean up metal debris from floors of warehouses and workplaces, also they are used to clean floors at homes by inducing an electrostatic field which pulls dust to the surface of the sweeper.

Perpendicular to both the current and the magnetic field.

depends on the content of the copper wire, if its 100% usually it will

Like poles refer to the situation where two magnets have their similar ends (north or south poles) facing each other. This positioning causes the magnets to repel each other due to their magnetic forces being in opposition.

Magnetism is characterized by the interaction between opposite poles, with like poles repelling and opposite poles attracting each other. The convention of labeling them as North and South poles dates back to when magnetic compasses were first used for navigation, aligning with Earth's magnetic field. Using East and West wouldn't provide the same clear reference for which ends are attracted or repelled.

They are flip sides of the same coin. A magnet passed back and forth rapidly over iron causes electricity and an electric current passed through a piece of iron causes a magnetic field. magnets also have 2 different sides that are called north and south. if north on one magents and the other magent is north too and you try to put the 2 together with them sides they will repel. repel means to not come together, like go apart from each other. but when south and north is coming together they will not repel but they will atrack to each other . atrack means to come together. like lovers.

Magnetic force. Now I know this is not a very satisfying answer, but it is the same sort of question as "why does gravity attract mass?" There are four fundamental forces, Gravity, Electromagnetism, the Atomic Strong and Weak forces. That's the universe we live in. So my suggestion is--just slide this one to the side for now.

Bar magnets are already magnetized. They don't need to add wire and electricity.

They use a powerful electromagnet. An electromagnet is essentially a coil of wire. When an electric current is passed through the wire, a magnetic force is created inside the coil. So to make a magnet, they rap the raw materials (special combinations of metal) in a wire and pass a current in the wire for a certain time. When the current is shut off, the material inside retains the magnetic properties and becomes what we call a Magnet.

Not all metals attract to magnets.

Examples are: aluminium, copper, titanium,brass, bronze, tin, nickel, platinum, gold, silver, lead, pewter

But im wondering what the Bleach zangetsu key chain is made out of?

A strong magnetic field has a higher magnetic flux density than a weak magnetic field. This means that a strong magnetic field exerts a greater force on nearby magnetic materials compared to a weak magnetic field. Additionally, strong magnetic fields are more effective for magnetizing materials or creating magnetic induction.

Place the magnet vertically on the equator, with the north end facing the North Pole.

To create a permanent magnet energy must be supplied to suitable materiel by immersing it in a magnetic field normally supplied by an electromagnet

Tying saplings to wooden poles helps provide support and stability to young, fragile plants as they grow. This practice helps prevent the saplings from bending or breaking under the weight of their own growth or external factors like wind, snow, or rain. Additionally, it promotes straight and upright growth, leading to healthier and more robust trees in the future.

The freely suspended magnet does not point exactly along the geographical North-South direction due to localized magnetic anomalies in the Earth's crust. These anomalies can disturb the magnetic field in local areas, causing the magnet to deviate slightly from true North. Additionally, external magnetic fields from sources like power lines or buildings can also influence the orientation of the magnet.

When one pole of a magnet is brought near each end of a hanging magnet, the hanging magnet will experience a force due to the interaction between the magnetic fields. Depending on the orientation of the poles involved, the hanging magnet may be attracted towards the other magnet if opposite poles are facing each other, or repelled if like poles are facing each other.

When a substance is magnetic, it means that it has the ability to create a magnetic field and attract or repel other magnetic materials. This property arises from the alignment of the magnetic moments of its atoms or molecules.

Soft iron is suitable for preparing pole pieces in headphones as well as loudspeakers instead of steel because soft iron materials have high permeability and low coercive force. They are easily magnetized and demagnetized. Examples of soft magnetic material are silica-steel (Fe-97 and Si-3), Sandust (Al-5, Si-10, Fe-85).

Soft iron materials have following characteristics:-

Thin hysteresis loop.

High permeability.

Low coercivity.

High susceptibility.

Low hysteresis loss.

Low eddy current loss.

Whereas materials made up of steel have totally different properties i.e.

High permeability and High hysteresis loss.

Large hysteresis loop.

High coercivity residual magnetism.

Magnetic objects are attracted to a magnet because of the properties of the magnetic field. When a magnetic object is brought near a magnet, the magnetic fields interact in a way that leads to attraction. This attraction occurs due to the alignment of magnetic domains within the object, causing it to be pulled towards the side of the magnet with the opposite polarity.

Art room temperature californium is paramagnetic.

magnets are strong and if you put a cell phone near it, it might damage it
