The attraction or repulsion that unlike or like charges have is due to the electrostatic force. Like charges (positive-positive or negative-negative) repel each other, while unlike charges (positive-negative) attract each other. This force is governed by Coulomb's law and is responsible for the interactions between charged particles.
The law of magnetic attraction and repulsion states that like magnetic poles (north-north or south-south) repel each other, and unlike magnetic poles (north-south) attract each other. This principle explains how magnets interact and is fundamental in understanding magnetic behavior.
Yes, lightning is caused by the attraction between positive and negative charges in the atmosphere. When the build-up of electrical charge in a storm cloud becomes strong enough, it overcomes the resistance of the air and creates a discharge in the form of lightning.
The strength of two magnetic poles is directly proportional to the force between them. As the strength of the poles increases, the force of attraction or repulsion between them also increases. Conversely, if the strength of the poles decreases, the force between them will weaken.
When charges are separated on objects, it is called static electricity. It occurs when the positive and negative charges build up on different surfaces due to friction or contact, leading to an imbalance of charges. This can result in phenomena like sparks, lightning, or attraction/repulsion between objects.
Polar liquids are attracted to a charged rod because the rod's electric field induces a temporary separation of charges in the liquid, creating an attractive force. This attraction overcomes any repulsion that might occur due to like charges on the rod and liquid.
