Presentation on Theme: Magnetism

Presentation on Theme: Magnetism : 1 Magnetism 2 Activating Strategy With a partner, take the list of everyday objects provided by the teacher and identify those objects that have or use magnets. Instructional Approach(s): Think-pair-share. The teacher should use the slide to activate students prior knowledge. 3 Essential question: how do the properties of magnets [...]

  • Magnetic force on a wire

What is magnetic force?

What is the magnetic force? The magnetic force is a consequence of the electromagnetic force, one of the four fundamental forces of nature, and is caused by the motion of charges. Two objects containing charge with the same direction of motion have a magnetic attraction force between them. Similarly, objects with charge moving in opposite [...]

Magnet Materials

Permanent Magnet Materials Permanent magnet lodestones contain magnetite, a hard, crystalline iron ferrite mineral that derives its magnetism from the effect the earth's magnetic field has on it. Various steel alloys can also be magnetized. The first big step in developing more effective permanent magnet materials came in the 1930s with the development of Alnico [...]

Grain Boundary Diffusion- Conserving HREE in NdFeB Magnets

Grain Boundary Diffusion- Conserving HREE in NdFeB Magnets Grain Boundary Diffusion is an important new advance in Neodymium magnet production technology. Heavy Rare Earth Elements (HREE) are delivered directly to critical areas of the magnet’s microstructure. These areas are where HREE are the most effective at increasing the properties of the magnet to withstand high [...]

  • Parylene Coated Magnets

Parylene Coated Magnets

Parylene Coated Magnets What is Parylene coating? Parylene is the common name of Poly-para-xylylene, and it was prepared by the researcher in University of Manchester in 1947. The parylene first applied to U.S military and aerospace industry after Union Carbide prepared parylene thin film by the deposition process. Nowadays, parylene coating are widely used in [...]

  • Strong Magnet Magnetization Orientation

Strong Magnet Magnetization Orientation

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 keep the magnet magnetism for a long time?

How to keep the magnet magnetism for a long time? Magnet, also known as permanent magnets, are objects that exist around the material and have their own magnetic fields. They are both natural and artificial. Artificial magnets are usually made of a metal alloy and have strong magnetism. Ferromagnetic refers to the magnetic state of [...]

  • Strong Magnet Performance Curve

Strong Magnet Performance Curve

Strong Magnet Performance Curve, Demagnetization of Permanent Magnets, Demagnetization curves for a Nd-Fe-B The value of the reverse magnetic field strength required to reduce the magnetic induction to zero when the magnet is magnetized by reverse magnetization in the reverse magnetization is called the magnetic coercive force (Hcb). However, the magnetization of the magnet is [...]

  • Magnet Demagnetization Method

Magnet Demagnetization Method

Magnet Demagnetization Method Strong magnets can be magnetized and demagnetized, because the magnet itself is or will be magnetic, so we can make a certain method to demagnetize according to the use of strong magnets. Magnet Demagnetization Method Vibration demagnetization method: The operation of this method is very simple, that is, the powerful [...]
