Do Magnet Coating Affect Magnet Strength?

Do Magnet Coating Affect Magnet Strength? Some customers ask whether the magnet coating will affect its magnetic strength from time to time? How big is the impact? Let's talk about this topic today. This is indeed an important factor to be considered. Although the distance of one or two millimeters between the magnet and another [...]

High Temperature Can Make Magnets Lose Magnetism Quickly

High Temperature Can Make Magnets Lose Magnetism Quickly A magnet will lose some magnetism immediately when it encounters a high temperature that exceeds its own tolerance. How much high temperature does it need? This depends on the coercive force of the magnet, which is usually expressed by the letter after the magnet grade, such as [...]

Earth’s Magnetic Field Reversal

Earth’s Magnetic Field Reversal Earth’s Magnetic Field Reversal Took Three Times Longer Than Thought A new study suggests the last field reversal 773,000 years ago took 22,000 years to occur, which could explain some of the inner workings of our planet’s core。 Earth’s magnetic field is known to flip direction with a somewhat unnerving regularity: [...]

Magnetic Pole Reversal Happens All The (Geologic) Time

Magnetic Pole Reversal Happens All The (Geologic) Time Scientists understand that Earth's magnetic field has flipped its polarity many times over the millennia. In other words, if you were alive about 800,000 years ago, and facing what we call north with a magnetic compass in your hand, the needle would point to 'south.' This is [...]

What Is Magnetic Reversal?

What Is Magnetic Reversal? Earth is like a giant magnet in several ways. Not only does it have a magnetic north and south pole that act similarly to the poles on bar magnets, but the planet is surrounded by a strong magnetic field, which is electrically charged and able to interact with magnetized matter. The [...]

Can't get enough of hands-on electromagnetic experiments? We have some more ideas for you to try: What is the magnetic power of a single coil wrapped around a nail? Of 10 turns of wire? Of 100 turns? Experiment with different numbers of turns and see what happens. One way to measure and compare a magnet's [...]

Electromagnets All Around Us

Electromagnets All Around Us Many electromagnets have an advantage over permanent magnets because they can be easily turned on and off, and increasing or decreasing the amount of electricity flowing around the core can control their strength. Modern technology relies heavily on electromagnets to store information using magnetic recording devices. When you save data to [...]

The History of Electromagnets

The History of Electromagnets The relationship between electricity and magnetism wasn’t thoroughly studied until 1873 when physicist James Maxwell observed the interaction between positive and negative electrical charges. Through continued experimentation, Maxwell determined that these charges can attract or repel each other based on their orientation. He was also the first to discover that magnets [...]

How Electromagnets Work

How Electromagnets Work What do a wrecking yard, a rock concert and your front door have in common? They each use electromagnets, devices that create a magnetic field through the application of electricity. Wrecking yards employ extremely powerful electromagnets to move heavy pieces of scrap metal or even entire cars from one place to another. [...]

1800 After History of Magnetism and Electricity

1800 After History of Magnetism and Electricity 1820 - Electromagnetism, Current In 1820, a physicist Hans Christian Oersted, learned that a current flowing through a wire would move a compass needle placed beside it. This showed that an electric current produced a magnetic field. Andre Marie Ampere, a French mathematician who devoted himself to the [...]

Before 1800 History of Magnetism and Electricity

Before 1800 History of Magnetism and Electricity 600 BC - Lodestone The magnetic properties of natural ferric ferrite (Fe3O4) stones (lodestones) were described by Greek philosophers. 600 BC - Electric Charge Amber is a yellowish, translucent mineral. As early as 600 BC the Greek philosopher, Aristophanes was aware of its peculiar property: when rubbed with [...]
