The invisible field you are talking about is called the magnetic field.
You may be wondering, what does it mean that magnetism is "an invisible force".Well, magnetism is an invisible force because the magnet reaches out and when it does, there is a magnetic field around it so the magnet does not need to be touching another magnet to pull or push it.
A magnetic Field
magnetic field, or field/
You can make magnetic field lines with a magnet. You an use a permanent magnet, or an electromagnet.
Magnetic field ; )
it sets up an invisible atmosphere around itself called a magnetic field. When a pm or nail is in that field, it becomes a little magnet too.
No. It is strongest at the poles.
Whatever it is that enables a magnet to push another magnet without ever touching it, is called the "magnetic field". It is an invisible attribute of a magnet that surrounds the magnet and exerts forces on other magnets and some non magnets, like iron.
The magnetic field. If it's an electromagnet, the electromagnetic field.
Surrounding a magnet with a magnetic shell can allow the magnetic field to move farther away from its source.
Magnetic field or magnetic flux lines, one of the manifestations of the electromagnetic force.
A magnet is a material or object that produces a magnetic field. This magnetic field is invisible but is responsible for the most notable property of a magnet. This property is the force that pulls on other ferromagnetic materials, such as iron, and attracts or repels other magnets.
This describes a magnet.
On the gray side of the magnet, if you take out a magnet and put it next to a magnet things you put on the fridge, It sticks to it! You see, the magnet's force is invisible so u can't see it. Or if you put it next to a magnet that sticks to that magnet, You might feel it's force or not. I tried it once :).
An electromagnet is just one kind of magnet. A magnet is a material or object that produces a field (called a magnetic field) that is normally invisible but that exerts a pull on ferromagnetic materials such as iron. One magnet may also repel another magnet, or may forcefully attract it. The difference between an electromagnet and most other kinds of magnet is that most other magnets always produce a magnetic field, but an electromagnet requires an electric field flowing through a loop or coil to produce the magnetic field. When the electric current is off, the object is no longer magnetic.
The field is strongest on the poles of the magnet (the ends of the magnet). More specifically, the 8 corners of the magnet are where the strongest magnetic field will occur. The weakest field occurs in the center of the magnet.
No. A magnet is a material that produces a magnetic field. The MF is invisible and is responsible for the magnet's force that pulls on ferromagnetic materials such as iron. It attracts or repels other metals.
They are kind of like a force around each other. They are negative and positive pulls. As you hold a paper clip to a magnet its an invisible field around the paperclip and the magnet. The paper clip also has magnet attracted metal so it will stick.
The volume surrounding a magnet will be filled with the lines of magnetic force. Since these are similarly polarized, they repel each other - eventually creating a sphere at a sufficiently large distance. This sphere is the magnetic field of that magnet.
The field strengthens as you get closer to the surface of the magnet.
Its invisible for a reason
