A magnetic field surrounds each magnet, and affects other magnets. That is correct, AND we know the other two are not possible candidates!
Magnets create a magnetic field around them which exerts a force on other magnets within that field. This force is generated by the alignment of the magnetic domains within the magnets, causing them to attract or repel each other without touching.
Magnets have magnetic fields that exert attractive or repulsive forces on other magnets within their vicinity. These fields interact with each other through magnetic force, causing the magnets to either attract or repel each other without physical contact. This phenomenon is a result of the alignment of magnetic moments within the materials.
magnets??
When the south poles of two magnets are almost touching, they will repel each other due to their like polarity. The force of repulsion will increase as the distance between the magnets decreases, reaching a maximum when the poles are in direct contact.
If the magnets are touching, then yes there is, if they are at a distance then the only friction they would have is from the air between them.
The hypothesis of magnets is that they contain invisible forces that attract or repel certain metals based on their polarity. This hypothesis explains the observed behavior of magnets interacting with each other and with magnetic materials.
Iron, Nickel and cobalt are attracted to magnets, these are field forces because they act on an object without touching it
When the south poles of two magnets are almost touching, they will repel each other due to their like magnetic poles. This repulsive force is a result of the magnetic field surrounding each magnet, which causes them to push away from each other.
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.
When the south poles of two bar magnets come together, they will repel each other due to their like magnetic poles. This force will push the magnets away from each other, preventing the south poles from directly touching.
Steel contains iron, which is ferromagnetic and can be magnetized. Aluminum, on the other hand, is not ferromagnetic but paramagnetic, so it is not attracted to magnets. This difference in magnetic properties explains why steel sticks to magnets but aluminum does not.
The distance at which magnets can attract each other depends on the strength of the magnets. Generally, the attractive force decreases as the distance between two magnets increases, following an inverse square law. For small magnets, the typical attraction distance is a few inches, but for larger or stronger magnets, it can be several feet.
