Magnets have two poles, a north pole and a south pole. The north pole of one magnet is attracted to the south pole of another magnet, and vice versa. This attraction is due to the magnetic field created by the movement of electrons within the magnet.
None, unless you charge one up
~hahaha
THey either attract or repel

How is Law of electric charge related to electric motor?
The Law of Electric Charge states that like charges repel and opposite charges attract. In an electric motor, this law is crucial for the operation of the motor. By applying electric currents to create magnetic fields, the motor uses the interaction of opposite charges to generate force and produce motion.
Does a lightning rod use electriacity and magnets?
A lightning rod does not use electricity or magnets. It works by providing a conductive path for lightning to follow safely to the ground, preventing damage to structures by directing the electrical charge away from them.
Is there a difference between magnets and electromagnets?
Yes, magnets produce a magnetic field due to the alignment of the electrons in the material, while electromagnets produce a magnetic field when an electric current flows through a coil of wire. Magnets have a constant magnetic field, whereas electromagnets can have their strength controlled by adjusting the current.
Examples for law of electric charges?
Like charges repel each other: Two positively charged objects will push away from each other when brought close. Unlike charges attract each other: A positively charged object will be attracted to a negatively charged object when they are brought close. Charge is conserved: The total charge in a closed system remains constant.
Examples of permanent magnets?
Some examples of permanent magnets include neodymium magnets, samarium cobalt magnets, and ceramic (ferrite) magnets. These magnets retain their magnetism without the need for an external magnetic field.
Bar magnets display a characteristic type of charge called?
Bar magnets display a characteristic type of charge called magnetic charge. These charges create a magnetic field around the magnet and can interact with other magnets or magnetic materials in their vicinity.
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.
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.
Why don't fridge magnets stick to each other?
Fridge magnets are made of materials that do not attract each other, such as plastic or glass. They rely on the magnetic force of the metal surface of the fridge to stick. If two fridge magnets have the same magnetic orientation, they will repel each other.
Can you charge your laptop battery with a magnet?
I don't think so...magnets are very harmful to computers.

What do flywheel magnets do?
One standard push mowers they help make the spark for the spark plug. On riding mowers and electric start push mowers they do the same and there is another set of magnets that charge the battery.
How are magnets used in making a car run?
magnets are used in the starter and the alternator. in the starter, electro magnets are used to run the electric starter motor and also to bring the pinion gear into the flywheel. in the alternator magnetic current is used to generate electricity to charge the battery. there may be some small magnets in the transmission to pick up metal fillings.
