### Why does rubbing a balloon create a negative charge?

When you rub a balloon on a sweater, for example, some electrons come off and end up on the balloon. The fibers have lost electrons giving them a positive charge. The rubber gained electrons giving it a negative charge. Since electrons have a negative charge, the balloon now has a negative charge.

### Can you have a negative charge?

There are two types of electric charge: positive and negative (commonly carried by protons and electrons respectively). If there are more electrons than protons in a piece of matter, it will have a negative charge, if there are fewer it will have a positive charge, and if there are equal numbers it will be neutral.

### What produces negative charge?

Electrons are said to carry negative charge, while protons are said to carry positive charge, although these labels are completely arbitrary (more on that later). Protons and electrons create electric fields, which exert a force called the Coulomb force, which radiates outward in all directions.

### How can a magnet have a negative charge?

In order to make a negative charge magnet, you will have to make a simple magnet. A simple magnet is created by running an electrical current through a metallic object. The charge from the electrical source helps to create a charge on the metallic object which, in turn, will generate a magnetic field.

### Do negative and positive charges attract?

Opposite charges attract each other (negative to positive). Like charges repel each other (positive to positive or negative to negative). The rubbing of certain materials against one another can transfer negative charges, or electrons.

### Is North positive or negative?

Generally, the south pole is termed positive, and the north negative.

### Does current flow from negative to positive?

Electrons flow from the negative terminal to the positive. Conventional current or simply current, behaves as if positive charge carriers cause current flow. Conventional current flows from the positive terminal to the negative.

### Is the earth negative or positive?

Description. Atmospheric electricity is always present, and during fine weather away from thunderstorms, the air above the surface of Earth is positively charged, while the Earth’s surface charge is negative.

### Do two negative magnets attract?

Electric charges and magnetism similar

Just as the positive (+) and negative (−) electrical charges attract each other, the N and S poles of a magnet attract each other. In electricity like charges repel, and in magnetism like poles repel.

### How can a magnet attract or repel even if they are not touching?

Magnets are surrounded by an invisible magnetic field that is made by the movement of electrons, the subatomic particles that circle the nucleus of an atom. The hyperactivity of these electrons gives magnets their ability to attract and repel.

### Are two magnets stronger than one?

Two magnets together will be slightly less than twice as strong as one magnet. When magnets are stuck entirely together (the south pole of one magnet is connected to the north pole of the other magnet) you can add the magnetic fields together.

### When opposite poles are facing each other?

If you line the magnets up so that two of the same poles face each other, the magnets will push away. This is called repulsion. Opposite poles attract each other, but similar poles repel. The Earth acts like a giant magnet.

### Is it possible to have a lone pole for a magnet?

There is never an isolated pole (a monopole). All magnets attract iron, such as that in a refrigerator door. The two poles are thus named the north magnetic pole and the south magnetic pole (or more properly, north-seeking and south-seeking poles, for the attractions in those directions).

### What is the simplest requirement for an electromagnet?

A wire that has electrical current running through it creates a magnetic field. In fact, the simplest electromagnet is a single wire that is coiled up and has an electric current running through it. The magnetic field generated by the coil of wire is like a regular bar magnet.

### How can you relate electricity to magnetism?

Electricity and magnetism are closely related: power lines generate a magnetic field and rotating magnets in a generator produce electricity. But the phenomenon is actually much more complicated, because the electrical and magnetic properties of certain materials are also coupled with each other.

### Can we separate electricity and magnetism?

D. Electricity and magnetism are separate yet interconnected phenomena associated with the electromagnetic force. Together, they form the basis for electromagnetism, a key physics discipline.

### Can you have electricity without magnetism?

No you can have a magnetic field without an electric field. Consider a rod with an equal number of positive and negative charges (such that they are equally spaced). This will result in a magnetic field but no electric field.

### Is electricity a magnetism?

Electricity is due to the presence and movement of charge carriers. While magnetism is the result of the interaction between moving charges. Electricity is known to be an invisible force, while magnetism is regarded as an outcome of current electricity.

### What law does electricity and magnetism follow?

Faraday’s Law of Induction describes how an electric current produces a magnetic field and, conversely, how a changing magnetic field generates an electric current in a conductor.

### Can a magnetic generator power a house?

A magnetic generator is the best alternative energy resource which you can avail easily in your homes. A magnetic electricity generator uses its powerful magnets for generating cheap electricity. Magnets have a very special property of polarity due to which it exerts enormous force.

### How can I get free electricity for my home?
