How to Choose the Bushless Motor Magnets? After you choose the slots and poles, you need to choose the magnets. This is not very easy task because you need high temperature magnets and are not so cheap and easy to find for your needed size. I bought custom made magnets from a Chinese SUPPLIER MPCO [...]

Radially oriented sintered NdFeB ring magnets for DC motor is becoming more and more popular for motor (Brushless DC [...]
Strong Magnet Magnetization Orientation How do you differ from the north pole of a strong magnet without being marked? Obviously, it is impossible to distinguish between eyes alone. The compass can be used to approximate the powerful magnet, and the pointer to the north pole of the earth points to the south pole of the [...]
How to distinguish the north and south poles of magnet? Magnets are widely used in various industries, because of magnetic adsorption and magnetic induction, many electronic products, hardware, machinery and other industries! So before many customers use magnets, there is a doubt, how to distinguish the north and south poles of the magnet, because the [...]
A custom experience sharing of magnetic pump magnet Can you customize the magnetic pump magnet? At the beginning, some customers asked me, I am very blind, because some applications of magnets are not very clear soon, customers may feel that I am not professional and ignore me, so it is very important to say that [...]

Why compass can be inaccurate Compasses are brilliantly useful but they can sometimes lead us astray, because of two quite different problems called declination (or variation) and deviation. Here's why. compass Declination (variation) Earth spins about an axis (a kind of invisible rod) running through the north pole (sometimes called the geographic north [...]
How do compasses work? Artwork: Earth behaves as though it has a giant bar magnet built inside it. But the magnet is the opposite way around to how you might think, with its south pole up near Earth's actual (geographic) north pole and vice-versa. A compass needle points north because the north pole of the [...]
Magnetic Field on Earth Earth has a magnetic field. If you imagine a gigantic bar magnet inside of Earth, you'll have a pretty good idea what Earth's magnetic field is shaped like. Of course, Earth DOESN'T have a giant bar magnet inside it; instead, our planet's magnetic field is made by swirling motions of molten [...]
North Magnetic Pole - "Magnetic North" redirects here. For other uses, see Magnetic North (disambiguation). The North Magnetic Pole is the wandering point on the surface of Earth's Northern Hemisphere at which the planet's magnetic field points vertically downwards (in other words, if a magnetic compass needle is allowed to rotate about a horizontal axis, [...]
Polar Reversals: South-Pole Pointing Compass Imagine your compass pointing south instead of north. Compass If you were alive to see it 800,000 years ago, it would have been the Magnetic South Pole. It takes 200,000 to 300,000 years for Earth’s magnetic field to flip polarity. Flipping polarity means the lines of attraction that enter the [...]
Magnetic North Shift, Shift In Poles Means Magnetic North Now East Of Grid North For First Time In 220 Years Magnetic north has moved from west of Grid North to the east for the first time in 200 years, causing a massive reworking of the Ordnance Survey's maps. While it's usually thought to be an [...]
