A temporary magnet is "charged" by aligning their electronic spins in one direction (each atom acts like a magnet this way, the the effect multiplies). It's what happens when you turn the power on an electromagnet.

What is a hard magnet?
Hard magnets are permanent magnets that do not require electricity to retain their magnetism and are not easily demagnetized. They are magnetically charged naturally and can be artificially, too.
What happened when the two negatively charged balloons were brought together?
they repell each other like magnets
Are smaller magnets stronger than larger magnets?
yes.in bigger magnets there are more magnetisom This is not true! In many cases larger magnets are stronger than smaller ones but not in all. I urge you to do research on reputable sites which can offer accurate answers to your questions. Magnet strength and effectiveness rely on size, age, gauss ratings as well as several other aspects. But do not take my word, please research further.
What magnets repel to?
Not only magnets, but metal repel. There are two kinds of charges that metal contain, positive and negative. If you push a positively-charged magnet towards another positively-charged magnet, they'll repel, maybe because one type of charge needs the other to attract. If this one type of charge comes close to another charge of the same kind, it won't receive what it needs, and feel "resent" to the other charge, then repel. If you push a negatively-charged magnet towards another negatively-charged magnet, they will also repel.
What does electricity have to do with magnets?
Electricity and magnetism are part of a single force called electromagnetism. An electrically charged object or particle generates a magnetic field, and an existing magnetic field creates a force that acts on charged particles in motion.
How are charged objects and magnets alike?
they are not
What happens when magnets get heated?
It loses its charged.
Are south poles of magnets negatively charged?
Yes
On a magnet which pulls and which repels?
Parts that have the same charge will repel. Opposite charges attract/pull each other. So positive sides of magnets attract negatively charged magnets and repel positively charged magnets. Negative sides of magnets attract positively charged magnets and repel negatively charged magnets.
How magnets are used in motors?
The alternator does. It is what keeps your battery charged while in use.
What is a hard magnet?
Hard magnets are permanent magnets that do not require electricity to retain their magnetism and are not easily demagnetized. They are magnetically charged naturally and can be artificially, too.
How and why do magnets attach?
They become attracted from the positive and negitively charged atoms. When these atoms come together, they attract to each other which makes the magnets attach.
How is an electromagnet used in a tv?
Magnets direct charged particles based on their mass and charge.
Do magnets blow up?
No. Magnets are just pieces of metal that are magnetically charged to attract to the nickel and iron on the earth's core. There is nothing done to the that causes them to blow up.
What happened when the two negatively charged balloons were brought together?
they repell each other like magnets
What is most likely to be attracted by a magnet?
Iron, nickel and some of their alloys are attracted to magnets (only some types of steel). Also, the oppositely charged poles of other magnets or electromagnets.
