Magnets can lose their magnetic properties if exposed to high heat or are made subject to high impact. The temperature at which magnets lose magnetic properties is referred to as the Curie Temperature for ferromagnetic materials.
Magnets lose their magnetic properties if they are droped down from a height and when they are heated.
1. Magnets attract iron and other ferromagnetic materials such as neodymium and cobalt. 2. Magnets attract or repel other magnets. 3. In addition one part of a magnet will always point north when allowed to swing freely.
Liquid nitrogen is not cold enough to supercool some superconducting magnets to make that magnet's superconductive properties emerge. It takes something like liquid helium to do that.
There are 2 properties of magnets.
Magnetism.
Magnetism.
Permanent magnets.
Permanent magnets.
they have magnetic properties that weaken with time.
Have north and south poles
repel force, attraction force,
the 4 magnetic materials are iron, steel, copper and nickel
Magnets have two poles north and south. Like poles repel and unlike poles attract.
it will lose its magnetism OR it will get weaker
PROPERTIES OF MAGNET1. Magnets attract objects of iron, cobalt and nickel.2. The force of attraction of a magnet is greater at its poles than in the middle.3. Like poles of two magnets repel each other.4. Opposite poles of two magnets attracts each other.5. If a bar magnet is suspended by a thread and if it is free to rotate, its South Pole will move towards the North Pole of the earth and vice versa.
