Study Notes
Magnetic Fields
- A magnetic field is a region around a magnet or a moving electric charge where magnetic force is exerted.
- Magnetic fields are generated by moving electric charges, such as electric currents in wires or the movement of electrons in atoms.
- The direction of a magnetic field is defined by the direction that the north pole of a compass needle would point in that field.
- Current conventionally travels from the positive terminal of a power source to the negative terminal.
- Moving electric charges also generate magnetic fields, and the direction of the field is determined by the direction of the charge's motion.
- The direction of a magnetic field can be visualized using the concept of magnetic field lines. These lines are imaginary lines that represent the direction of the magnetic force at any point in the field.
- The force experienced by a charge moving in a magnetic field is perpendicular to both the direction of the charge's motion and the direction of the magnetic field. This can be determined using the right-hand rule, where the thumb points in the direction of the current, the fingers point in the direction of the magnetic field, and the palm points in the direction of the force.
