Magnetic and electrical fields are related, and magnetism, along with gravity and strong and weak atomic forces, is one of the four fundamental forces in the universe. But none of those facts answers the most basic question: What exactly makes a magnet stick to certain metals? Or why don't...
The pull of stronger magnets: super-powerful magnets would boost the performance of electric cars and other green technology. Why is it so hard to make them?For Christmas, magnetics researcher William McCallum got one of the latest cool toys: 'Buckyballs: Th...

The internal structure of permanent magnets creates magnetic fields. They are usually not prone to losing their magnetism easily. Ferromagnetic metals can be made into permanent magnets that do not lose their magnetic field, regardless of external influences. They can withstand demagnetising ...
The magnetic force is strongest at the poles because the field lines are closer together, resulting in a stronger push or pull. In the middle of the magnet, the magnetic field lines are more spread out, leading to a weaker force. Rate this question: 5. Which two metals will be ...
It is also true that I am also pushing up with 3 lb of force. Does that add up to 6 lb? No! These forces are not even in the same direction. You're pushing down and I'm pushing up. We're measuring 2 different things. Think of what you can measure with that pull force gauge...
When magnet are the force of magnetism is stronger? The magnetic field of a bar magnet is strongestat either pole of the magnet. It is equally strong at the north pole when compared with the south pole. The force is weaker in the middle of the magnet and halfway between the pole and ...
External forces like magnetic fields can make the domains grow and line up their tiny magnets. This makes a permanent magnet. Heating a material also gives energy to the tiny magnets to move around. This lets domains line up their tiny magnets. ...
They have a low coercive force which means they can be demagnetized easily by external forces. Hence, it’s important to handle them with extreme caution. Alnico magnets have the highest magnetic flux density. There are alnico magnets with anisotropic properties (magnetized in only one axis-are...
A magnet creates around itself a region of space with special properties. This region is known as a magnetic field. When two magnets come near each other, their fields create forces that attract or repel. The Earth is itself a huge magnet, and the force its field exerts on other magnets ...
