Study Notes
Electromagnetic Induction
- The process of generating current in a conductor by placing the conductor in a changing magnetic field is called electromagnetic induction or induction.
- This process is called induction because the changing magnetic field induces an electric field in the conductor, which in turn produces an electric current.
Requirements for Electromagnetic Induction
- One requirement for electromagnetic induction to take place is that the conductor must be in a changing magnetic field.
Direction of Induced Current
- The direction that the induced current flows is determined by the direction of the changing magnetic field and the orientation of the conductor.
- For the induced current to flow, the conductor must be perpendicular to the magnetic lines of force.
Measuring Current
- The instrument used to measure current in the animation is an ammeter.
Characteristics of Electromagnetic Induction
- During electromagnetic induction, alternating current (AC) is generated in the conductor.
- The changing magnetic field causes an electric field to be induced in the conductor, resulting in the flow of current.
- The direction of the induced current is determined by the direction of the changing magnetic field and the orientation of the conductor.
