MAGNETIC POLES The magnetic force surrounding a magnet is not uniform. There exists a great concentration of force at each end of the magnet and a very weak force at the center. Proof of this fact can be obtained by dipping a magnet into iron filings (fig. 1-8). It is found that many filings will [...]
What is the Geographic (True) North Pole? The Earth rotates on the geographic north and south poles. The geographic north and south poles are where lines of longitude (meridians) converge in the north. The south and north pole are directly opposite to one another. The North Pole is located in the middle of the Arctic [...]
What is the Magnetic North Pole? The Earth is one big magnet. The Magnetic North Pole (also known as the North Dip Pole) is a point on Ellesmere Island in Northern Canada where the northern lines of attraction enter the Earth. A compass needle rests freely in its casing so it can maneuver itself. When [...]
True North or Magnetic North? More than once, out hiking or paddling, I followed my instincts (the campsite is right over there!) rather than my map and ended up off course. Good pilots and navigators trust instruments over instincts. Compasses point at magnetic north. Scouters have assumptions or impressions about Scouting. True North or [...]
Magnetic North Pole Basically, the Magnetic North Pole is where a compass points. This is not the northernmost point on the globe. It is a point in the Arctic that is always on the move, reacting to magnetic changes in the Earth’s core. Every few years scientists venture into inhospitable territories to locate the pole. [...]
Hall Effect Sensor We could not end this discussion on Magnetism without a mention about magnetic sensors and especially the very commonly used Hall Effect Sensor. The hall effect sensor is a type of magnetic sensor which can be used for detecting the strength and direction of a magnetic field produced from a permanent magnet [...]
Arc Magnets An arc magnet is a type of magnet that is shaped like a curved or bent arc. It is typically made of a ferromagnetic material such as iron or steel, and it is magnetized using an electrical current. Arc magnets are often used in motors and generators, as well as in other applications [...]
Ring magnets are versatile and can be used in a variety of applications, including scientific experiments, medical equipment, and manufacturing. They are shaped like a ring with a hole in the center and have north and south poles that can be segmented in different ways around the ring. The unique polarization of ring magnets allows [...]
Magnetic Reversals - Scientists tell us that our magnetic poles have reversed in the past, and that they will again. The last one occurred 780,000 years ago. The average time period between reversals is 450,000 years, but there isn’t really any pattern, it is random. We are overdue by average only. Scientists don’t really know [...]
Neodymium Radial Magnetized Ring Magnets Application Schematic Regarding the radial magnetization of magnets, many people do not know much about the contact with them, so they do not have a strong concept of radial magnetization. Radial magnetic ring magnetization is actually diametrical magnetization, and their strong magnetic surface is on the side of the ring. [...]
How does Encoder Magnetic Ring See the Number of Poles? The magnetic ring on the encoder is mostly made of ferrite, such as sintered ferrite, injection molded ferrite, and the number of magnetized poles is generally more. How to see the number of poles for the encoder magnetic ring? Some netizens have made difficulties. The [...]
Function and Use of the Magnetic Pole Sheet We can't see the magnetization method of magnet products with the naked eye. We don't know whether it is ordinary magnetization or multipole magnetization. We can only check it by using the magnetic pole observation piece, and judge the magnetization method and the number of magnetization poles [...]
