The defining characteristics of magnetic, electric charge, and electric circuit interactions are:
1. Magnetic Interactions:
- Magnetic interactions involve the behavior of magnets and magnetic fields.
- Magnets have two poles, north and south, and like poles repel each other while opposite poles attract.
- Moving charges produce magnetic fields, and a magnetic field can exert a force on a moving charged particle.
- The strength of the magnetic field depends on the distance from the magnet and the direction and velocity of the moving charge.
2. Electric Charge Interactions:
- Electric charge interactions involve the behavior of electric charges.
- Electric charges can be positive or negative, and like charges repel each other while opposite charges attract.
- The strength of the electric force depends on the distance between the charges and the amount of charge they have.
3. Electric Circuit Interactions:
- Electric circuit interactions involve the behavior of electric circuits.
- Electric circuits consist of a power source (such as a battery), wires, and various components (such as resistors, capacitors, and switches).
- The flow of electric charge (current) through a circuit is determined by the voltage of the power source and the resistance of the components.
- The behavior of electric circuits can be described using Ohm's law, which relates voltage, current, and resistance in a circuit.
