True. These are known as magnetic reversals.

it is not magnetic because, i have many of them.
Tourmaline is not magnetic as it is not a magnetic material. Magnetic materials are attracted to a magnet, whereas tourmaline does not exhibit this property. It is a crystalline mineral composed of various elements, and its unique properties make it a popular choice for jewelry and various applications.
Yes, a non-magnetic drill collar can be magnetized through various processes such as applying a magnetic field or inducing a magnetic charge. This can be done to aid in drilling operations or to improve the performance of the drill collar in specific downhole conditions.
Devices such as electric motors, transformers, inductors, and magnetic-based sensors utilize the magnetic effect of current. These devices rely on the interaction between electric current and magnetic fields to operate effectively in various applications.
Yes, magnetic minerals occur naturally in the Earth's crust. These minerals can be found in various forms, such as magnetite, lodestone, and hematite, and possess magnetic properties due to their composition of iron and other elements.
When the electric current is reversed on an electromagnet, the direction of the magnetic field is also reversed. This means that the north and south poles of the electromagnet switch places. This change in polarity can have various effects depending on the application, such as reversing the direction of motion in a motor or changing the direction of attraction or repulsion in a magnetic system.
No. For one thing, the moon does not have a polarity. The sun's magnetic field is constantly shifting, but it is currently not doing anything out of the ordinary. Third, shifts in magnetic fields do not affect natural disasters on Earth.
During a magnetic reversal, the Earth's magnetic field weakens, flips, and then eventually re-establishes itself with the opposite polarity. This process can take thousands of years to complete and can have various effects on navigation systems, animals relying on Earth's magnetic field, and even the climate.
Geologic maps use color to represent various types of geologic features or units (a particular type of rock with a known age range).
You don't have to be a scientist to observe that fact. All you have to do is take any magnet and hang it up on a thread, so it's free to rotate and point wherever it wants to point. When you do that, you find that every magnet that's free to turn always turns to point at the same place ... a spot in far northern Canada. When you do this experiment with thousands of magnets in thousands of places all over the earth, and keep records of the direction that magnets point in various places, it all goes together to give a beautiful diagram of the earth's magnetic field. People who do a lot of traveling over long distances have used this fact for thousands of years to build a device that helps them find their way around the surface of the earth. The device is called the 'magnetic compass'.
Magnetic production refers to the process of generating or creating magnetic fields using various techniques or materials. This can involve using magnets, electromagnets, or magnetic materials to produce a magnetic field for various applications such as magnetic levitation, data storage, or sensing.

A magnetic rock is called magnetite. It is a naturally occurring mineral that exhibits strong magnetic properties. Magnetite can be found in various rock formations and is used in various industries for its magnetic properties.
Geologic units of similar ages are typically shown on a geologic map using the same color or pattern to represent them. This helps to visually differentiate between different units and understand their distribution across a region. Stratigraphic relationships and relative ages may also be indicated to show how these units are connected in terms of geologic time.

yeah
Magnetic therapy is the use of magnets to relieve pain in various areas of the body.
