How the magnetic fields changes as you move away from a magnet?
The strength of the magnetic field decreases as you move away from a magnet. The field follows an inverse square law, meaning that it diminishes rapidly with distance. The further away you are from the magnet, the weaker the magnetic field will be.
How can a magnet make something move?
A magnet can make something move by exerting a force on certain materials like iron, nickel, and cobalt. When these materials are attracted to the magnet, they can move towards or away from it depending on the orientation of the magnet. This movement is caused by the magnetic field surrounding the magnet interacting with the magnetic properties of the material.
What are the 2 magnets pushing and pulling against each other in a motor called?
Magnets in motors do not push or pull each other at all. When electricity is passing through the copper wire of the Rotor, (the rotating part of the motor and shaft) the magnetism of the fixed magnet, forces the copper wires in the Rotor, to move away from the magnet. This force created by the combination of current in the copper wire, and the magnetic field of the magnet; creates a force strong enough to cause the rotor to move away from the magnet. The overall outcome is that the rotor starts to rotate permanently . This force is referred to as the electro- magnetic field force. If you use more separate magnets you will get more power out of the motor. It is common for larger motors to have 8 or more permanent magnets in them, but they do not push or pull against each other. They actually push the copper wires, providing the wires carry electricity.
Does glass move away from magnet?
No! there's no magnet attraction between glass and metal, I don't think the glass wont do anything.
Can a magnet move a car?
A magnet can move a car, if the magnet is strong enough.
Can magnets attract a copper wire?
No, copper is not magnetic. That said, if the copper wire has an electric current flowing through it then it will generate its own magnetic field around the wire. It seems feasible that this could be enough to move the wire if you have another magnet near it.
What happens when you move the bar magnet far from the nails?
When you move the bar magnet far away from the nails, the magnetic field surrounding the magnet weakens significantly. As a result, the magnetic force acting on the nails decreases, causing them to lose their magnetized state and fall off.
Is a magnetic field constand everywhere around the magnet?
Generally speaking yes, but for the big magnets, maybe because some areas of the magnet may suffered from more shock than other areas and so the poles may have been disrupted.
What happens to the strength of the magnetic field as you move away from a magnet?
The strength of the magnetic field decreases as you move away from a magnet. This decrease is inversely proportional to the square of the distance from the magnet. Magnetic fields follow an inverse square law, meaning the field strength diminishes rapidly with distance.
Where is the field strength the greatest around a magnet and how does it change?
The magnetic field strength is greatest near the poles of a magnet, where the magnetic field lines are most concentrated. As you move away from the poles, the field strength gradually decreases. The strength diminishes with distance, following an inverse square law in free space, meaning it decreases rapidly as you move further away from the magnet.
A horseshoe magnet is moved back and forth across a piece of copper wire an electric current is detectable in the wire?
yes, it will be very small but the inductance from the magnet should stimulate a current in the wire as it will cause electrons to move.
If a bar copper is brought near a magnet the copper bar will be?
I have just taken the test and the answer is.. b.) unaffected by the magnet The copper bar will become reactive if/when magnet is in motion. example; if strong magnet is slid swiftly along copper bar by hand, reaction will occur as a reactive force or drag and can be easily observed by anyone willing to test it themselves. This reaction is a form of Induction.
