Magnetism

Some magnetic rocks, like lodestone, can have value for their unique properties and use in various applications. However, not all magnetic rocks are valuable, and their worth will depend on factors like rarity, size, and quality.

No. It only needs to pass through a magnetic field to become magnetized. It does not need to come into physical contact with the magnet producing that field. This is because the process of magnetization has to do with electromagnetic induction rather than physical contact.

You can perform a simple experiment at home to prove this point. You'll need a bar magnet, a paper clip, and a thin sheet of paper. Place the paper between the magnet and the clip. Rub the clip against the paper on top of the magnet, and observe that the clip will still become magnetized even though it is not in physical contact with the magnet.

Permanet Magnet

It should only be capitalized if it is the beginning of a sentence, if is part of a proper noun, or if it is a word in the title of a book, article, movie, story, etc.

The full motion is F=qvB where v and and B are vectors and the full motion is

F= -qv.B + qvxb = qvB(-cos(angle) + vxBsin(angle)) there will be a scalar parallel to the field and the vector motion perpendicular to the field. This scalar field and motion is the real cause of so-called trapped particles.

The vector motion is that of a mass spectrograph. The charged particle moves in a circle when perpendicular to the magnetic field.

The magnetic properties of a material depend on its atomic structure, particularly the alignment and movement of its electrons. Materials with unpaired electrons and aligned magnetic moments exhibit magnetic properties. Temperature, external magnetic field, and crystalline structure also play a role in determining the magnetic behavior of a material.

magnetic field. This is the area around a magnet where its magnetic influence or force can be detected or felt.

The Earth's core which is thought to consist of large quantities of molten iron in the center rotates with the earth creating a magnetism which protect us from solar flares e.t.c without this magnetism solar "winds" would wipe our atmosphere away from us in a matter of moments

The north and south poles.

Magnetism is produced through electric currents. In the case of a permanent magnet, it is the electrons circling around the atomic nucleus that produces the magnetism (more atoms have one orientation than the opposite orientation).

At the two points or ends on a magnet, called the north and south poles.

The Earth's North Pole is a magnetic south pole and the South Pole is a magnetic north pole. This means that the North Pole of a compass needle points towards the Earth's magnetic South Pole, and vice versa.

When iron fillings are sprinkled near a magnet, they will be attracted to the magnet and align themselves along the magnetic field lines. This occurs because the iron fillings are small magnetic dipoles with north and south poles that align with the magnetic field of the magnet.

The rate of magnetic pole shift can vary, but currently the magnetic north pole is moving at a rate of approximately 34 miles per year towards Russia. This rate has been gradually increasing in recent years.

it becomes a magnet in it s own right with north and south poles

Antimatter particles have the opposite electrical charge and magnetic characteristics compared to their matter counterparts. For example, the positron has a positive charge while the electron has a negative charge. Similarly, the magnetic properties of antimatter are opposite to those of matter.

It depends on the type of magnet.

The Curie Point is the point above which a material cannot be a permanent magnet. For iron-type magnets, this is about 770C.

Of course, not all magnets are caused by ferromagnetism. An electric current produces a magnetic field, regardless of the temperature. The earth's core approaches a temperature of 5000 C, but the Earth still has a magnetic field caused by swirling currents in the core of the earth.

You can determine the direction of a magnetic field by using a compass needle, which will align itself along the field lines of the magnet. The direction in which the North pole of the compass needle points indicates the direction of the magnetic field lines.

The slug can reach a velocity of Mach 7, so the amount of kinetic energy depends on the mass of the slug.

Some examples of magnetism in living organisms include migratory birds using Earth's magnetic field for navigation, magnetotactic bacteria aligning with magnetic fields to move towards ideal environments, and some marine animals using magnetic particles in their bodies to detect direction and depth in the ocean.

to describe earth's magnetic field, there are three magnetic elements of earth listed as under,

1. angle of declination

2. dip

3. horizontal component of earth's magnetic field

An electromagnet can be turned on and off by controlling the electric current, allowing for greater control and versatility in its applications. Additionally, the strength of an electromagnet can be easily adjusted by changing the current, making it more powerful than a bar magnet. Electromagnets can also be designed to have specific shapes and sizes to suit different needs.
