Magnetism

Quite simply, magnetism is stronger than gravity. In order to see a gravitational attractment you need a big difference in the force while magnetism all you need is opposite poles to attract each other. Imagine the difference between the whole earth and a small pebble. That's the difference you need in-order to achieve gravitational attractment.

The magnitude of the magnetic field around a permanent magnet is greatest at the poles of the magnet. This is where the magnetic field lines are most closely packed and the field strength is the highest.

Diamagnetism, in which materials have a weak repulsive response to magnetic fields, is most characteristic of most materials.

It depends what it is made of. If it has silver, gold, iron, copper, magnesium, nickel, or and other metal that is a conductor in it. It probably can because most magnets have traces of iron and magnesium.

Materials that are non-magnetic, such as wood, plastic, and glass, tend to repel magnets. Additionally, materials with specific physical properties like being too thick or too soft can also repel magnets. Temperature can affect magnetic attraction, with extreme heat or cold potentially causing repulsion.

No, the iron nails inside the steel container will not be attracted to a magnet outside the container because the steel container will shield the nails from the magnetic field. Steel is not magnetic, so it will not affect the iron nails inside the container.

2, a positive and a negative

yes, a magnet has two poles, a north pole and a south pole. and if you break the magnet, each magnet will obtain its own north and south poles. no matter how many times you break a magnet, they will obtain their own north and south poles

Some non-magnetic metals are: aluminium, platinum, copper, lead.

No, humans do not have magnetic poles like a magnet. While the human body generates a very weak magnetic field due to the electrical currents in the body, it is not in the same way as a magnet that has distinct north and south poles.

Most CD players use electromagnetic switches called relays. Have you ever turned on the power on your CD player or another appliance, and heard a click immediately before it went on? That's a relay doing its job. In a relay, a small current runs through a coil which is right next to a switch with a magnet in it. The coil pulls on the switch, closing it and turning on the device. Relays are useful because they use a small current to control a much larger one. As a result, they are often used in the power supplies of electronic devices such as CD Players

The magnetic fields of any magnet are greatest closest to the poles (north and south). The strength of the magnetic field decreases as you move away from the poles towards the center of the magnet.

Materials that typically stick to iron include magnets, certain metals like steel, and some adhesives designed specifically for iron surfaces. However, other materials like plastic or wood do not naturally stick to iron.

While Earth itself cannot create magnets out of ferromagnetic materials, it does have a magnetic field that originates from its core made of iron and nickel. The movement of these materials creates a magnetic field that extends around the planet, influencing compasses and other magnetic materials on Earth's surface.

Many metals cannot be picked up by electromagnets (at room temperature). For instance, aluminum, gold, mercury, and copper will not be attracted to an electromagnet.

Iron sticks to an electromagnet at normal temperatures. If iron is too hot, it loses its magnetic abilities. This is true of all metals: if they're cold enough they exhibit magnetic properties, if they're too hot they don't show magnetic properties. Even mercury (liquid at room temperature) can be made magnetic if it's cooled to very low temperatures.

All magnets no matter how small have two opposing poles, a north pole and a south pole. The Earth also has a magnetic field and so it too has two poles, a North and a South Pole. The Earth also spins on its axis, the ends of this axis are also called Poles. There are two ends, a North and a South pole which are close to but not exactly in the same positions as the Earth's two magnetic poles.

The electromagnet with the most coils and high current flowing through would have the greatest magnetic field strength. Increasing the number of coils and current both contribute to a stronger magnetic field.

I suggest that you incinerate it.

The most strong natural magnet is lodestone, a naturally occurring magnetic mineral composed of magnetite. Lodestone has been used since ancient times for compass needles and in various applications where a strong magnetic field is required.

The switch in direction of Earth's magnetic north and south poles, known as geomagnetic reversal, is a natural phenomenon that has occurred several times in Earth's history. During a reversal, the magnetic field weakens and flips in polarity, causing the north magnetic pole to move towards the geographic south pole and vice versa. These reversals are a normal part of the planet's geologic processes and do not happen on a regular or predictable schedule.

The compass needle will align itself in the direction perpendicular to the flow of current, pointing to the east. This is based on the right-hand rule in electromagnetism, where the thumb points in the direction of current flow and fingers show the magnetic field direction.

Rubbing a nail with a magnet will align some of the magnetic domains in the nail. This will have the effect of making the nail into a magnet. The nail won't be a strong magnet, but it will come away with some residual magnetism. Suggestion: try a simple experiment with a nail and a magnet and some small paper clips to see if this works.

Yes, an electric field can exist without a magnetic field. Electric fields are produced by electric charges, while magnetic fields are produced by moving electric charges. So, in situations where there are stationary charges or no current flow, only an electric field is present.

A good periodic table will have a symbol telling you which elements are ferromagnetic (strongly attracted by magnets), paramagnetic (weakly attracted by magnets), or diamagnetic (weakly repelled by magnets).

Pyrolytic carbon is fairly strongly diamagnetic, as is bismuth. A lot of other elements (including mercury, silver, lead and copper) are diamagnetic to a lesser degree.

I've linked to a table showing which are which for many (but not all) elements.
