because the charges are opposite that causes the material to repel. because the charges are opposite that causes the material to repel.
The like charges attract and unlike charges repel.
attraction and repulsion depends on the charges of the materials you are using if two objects have the same charge then repulsion is going to occur but if two objects have opposite charge attraction will occur. the charge of the material is depended in how many protons (+) and electrons (-) and object has for example if your robe a plastic stick on the fur the fur would be positive and the plastic stick will be negative.

That the effects obey the square of the distance "law".
When two unlike charges are brought together they will attract. This is because one is usually negatively charged while the other one is usually positively charged.

MagnestismThe Law of Attraction and Repulsion states that like charges repel each other, and unlike charges attract. For example, two positively charged objects would repel, whereas a positively charged object and a negatively charged object would attract.
That the effects obey the square of the distance "law".
Adhesion is attraction between unlike substances.
It would be more accurate to say that lighting is caused by the operation of Coulomb's Law which involves both the attraction of unlike charges, and the repulsion of like charges. When a thundercloud contains a substantial negative charge, the excess electrons in the cloud repel each other. Meanwhile, they are also attracted to the ground.
To create a permanent magnet energy must be supplied to suitable materiel by immersing it in a magnetic field normally supplied by an electromagnet
like charges repel...unlike charges attract
In physics we know that repulsion is the tendency of particles or bodies of the same electric charge or magnetic polarity to separate or repel. Attraction is the opposite, and we see bodies of the same magnetic polarity attracted to each other.
It works on the principle of "MAGNETIC LOCKING". When two unlike poles are brought near each other, there exists a tremendous force of attraction between those two poles.
