Why don't fridge magnets stick to each other?
The reason why they don't stick together is because magnets have a positive and negative charge. if you put a positive charge side together with another positive side it won't stick because they are the same charge. if they are opposites they will stick.
How are electrons kept in an atom?
a proton in at atom has a positive charge + and an electron has a negative charge - and they attract one another like magnets
What is a positive charge and particles called that have no charge?
A positive charge is a positive electrical charge. Particles with no charge are called neutral particles.
An electrical charge in motion called?
An electrical charge in motion is called a current.
Explain why the atoms need to be ionized before element x atoms can be deflected in a mass spectrometer?
The atom needs to have a charge to be deflected (as an electromangets are being used - magnets work with charge) so by ionising the atom, it loses an electron and gains a positive charge.
Will magnets have pulling capacity?
magnets have potential energies associated with them and whatever object they are interacting with (must have charge to interact...). this energy does work as the force is exerted on said object, the direction being dependent on the charge. so yeah magnets can pull stuff
What effects magnets?
Current flow or the change of charge in time.
Does a battery last longer when it is surrounded by magnets?
No, batteries don't charge faster when around magnets. It charges at the same speed.
What happens to magnets if you heat it too much?
It will lose its magnetic charge.
Is there a difference between magnets and electromagnets?
"electro magnets" are magnetic ONLY when electricity travels through a coil of wire surrounding them. "Magnets", as you state it, are permanent magnets and remain so independent of and not dependent upon any additional electrical charge.
Why don't fridge magnets stick to each other?
The reason why they don't stick together is because magnets have a positive and negative charge. if you put a positive charge side together with another positive side it won't stick because they are the same charge. if they are opposites they will stick.
What happens when a positive and a negative charge meet?
if you are using magnets, they stick together.
How are electrons kept in an atom?
a proton in at atom has a positive charge + and an electron has a negative charge - and they attract one another like magnets
How is an electromagnet used in a tv?
Magnets direct charged particles based on their mass and charge.
How do you produce the electricity by magnets?
By creating a difference in potential. Charge will flow in those conditions.
Why can some metals act as permanent magnets?
Some metals can act as permanent magnets because they are able to hold a magnetic charge. These include iron, steel, and copper.
What charge do magnets have?
positive, negative, and neutral all of these charges are in an atom, and they are called [protons (+) Neutrons (0) <-- both are in the nucleus] and electrons (-) which orbit the nucleus of the atom.
