Magnetism

An iron nail is used to make an electromagnet because iron is a ferromagnetic material, which means it can easily be magnetized and retains its magnetism. When a current flows through the wire wrapped around the iron nail, it creates a magnetic field, turning the nail into a temporary magnet.

Well every object in the universe at least has some magnetism, but no. It's too minute. Not to be mean, but this question is kind of a given because Earth's magnetic field is too weak to attract objects, and a wooden chair has barely any magnetism, so it's kind of like asking, "Will my cup go flying into space at a trillion miles an hour?"

An electro magnet is an electrically charged coil of wire, called a solenoid, it usually has a magnetic metal core in the centre, iron would be good. The coil has to have an electrical current run through it to magnetise the metal.

The north poles of magnets repel each other, while the south poles attract each other. This is due to the orientation of the magnetic field lines.

A paperclip will be attracted to a magnet in water just like it would be in air. The water may slightly decrease the strength of the attraction due to the presence of water molecules, but the paperclip will still be drawn towards the magnet. If the paperclip is non-magnetic, then it will not be attracted to the magnet in any environment.

The strongest type of magnet typically found in a normal household is a neodymium magnet. These magnets are known for their strength and are commonly used in various household items such as refrigerator magnets and magnetic clips.

Cumberlandite is magnetic due to the presence of magnetite, an iron oxide mineral, in its composition. Magnetite has magnetic properties that make cumberlandite attracted to magnetic fields.

You would hear a faint tapping sound on the unmagnetized iron nail. As you move the stethoscope towards the strong magnet nail, the tapping sound would gradually become stronger and louder due to the attraction between the two magnetic objects, creating a more pronounced noise.

Autunite is not magnetic. It is a hydrated calcium uranyl phosphate mineral that does not exhibit magnetic properties.

Contrary to popular belief, most metals cannot be magnetised. The only common metals that can be magnetised are iron, cobalt and nickel. Mild steel, an alloy that contains over 98% iron, can also be magnetised because of its high iron content. Some steels, such as some stainless steels, have larger percentages of other metals which prevent them from being magnetised the same way.

The Hall coefficient of germanium typically ranges from 0.003 to 0.006 m^3/C. It is a material property that characterizes the ability of a material to conduct current perpendicular to an applied magnetic field.

The magnetic fields of opposite charges appear as circular loops around each charge. The direction of the magnetic field lines is counterclockwise for positive charges and clockwise for negative charges when viewed from above. The strength of the magnetic field decreases as the distance from the charge increases.

No, "north seeking" should not be capitalized unless it is at the beginning of a sentence.

You get two smaller magnets. Each piece will still have its own north and south poles, making them individual magnets.

A magnetic environment refers to the conditions or surroundings in which a magnetic field is present. It can include factors such as the strength, direction, and distribution of magnetic fields that influence the behavior of magnetic materials or objects within that space. Magnetic environments are found in various settings, such as around magnets, electromagnetic devices, or in the Earth's magnetic field.

magnetic field is a imaginary area around a manetic material where other magnetic subestences experience some force but flux is the imaginary lines of force that arise from magnet which indicate direction of force around it.

No, diamonds are not attracted to magnets because they are not magnetic materials. Diamonds are made of carbon atoms arranged in a crystal lattice structure that does not exhibit magnetic properties.

Foil is made of aluminum, which, in this case, does not have magnetic properties.

No, oil is not a magnetic material. Magnetic materials are those that can be attracted to a magnet, whereas oil is non-magnetic and does not exhibit any magnetic properties.

OHIP does not typically cover magnetic therapy as it is considered an alternative or complementary treatment. OHIP generally covers medically necessary services provided by physicians or health care practitioners. Magnetic therapy is often not considered a standard part of conventional medical treatment.

No, a dipole-dipole force is an intermolecular force that occurs between polar molecules. This force is caused by the attraction between the positive end of one polar molecule and the negative end of another polar molecule. It is not associated with individual particles containing two poles with negative charges.

Magnets can repel each other for an indefinite amount of time as long as they are placed in a position where their poles are facing each other in such a way that repulsion occurs. This repulsion can persist as long as the magnets remain in close proximity to one another.

No. The true north pole and the magnetic north pole are in different locations. The compass will point at the magnetic north pole. If you happened to be somewhere between the two north poles, the compass will point exactly backwards!

Stroking a needle with a magnet aligns the magnetic domains in the needle material in the same direction, causing the needle to become magnetized. This alignment of domains creates a magnetic field in the needle, giving it magnetic properties.
