Magnetism FAQ

Magnetism FAQ Basic Electricity Question 1 A permanent magnet is a device that retains a magnetic field without need for a power source. Though many of us have experienced the effects of magnetism from a permanent magnet, very few people can describe what causes permanent magnetism. Explain the cause of permanent magnetism, in your own [...]

Permanent Magnets Magnetism and Electromagnetism

Permanent Magnets Magnetism and Electromagnetism Centuries ago, it was discovered that certain types of mineral rock possessed unusual properties of attraction to the metal iron. One particular mineral, called lodestone, or magnetite, is found mentioned in very old historical records (about 2500 years ago in Europe, and much earlier in the Far East) as a [...]

Temperature Coefficients (α and β) of Permanent Magnets

What are Temperature Coefficients (α and β) of Permanent Magnets? A permanent magnet’s magnetic properties change as a variation of temperature. For a permanent magnet, remanence (Br) and intrinsic coercivity (Hcj or Hci) are two major parameters, it is important to consider their changes with corresponding temperature variation at work. In order to describe the [...]

Types of Temperature Losses of Magnets

Types of Temperature Losses of Magnets (= loss of magnetisation due to high temperature) Depending on the temperature, we distinguish between three different types of losses: Reversible temperature loss Temperature area: just above the maximum working temperature The magnet is less magnetic as long as it is hot. Once it is cooled down, it regains [...]
