Magnetism & Electromagnetism

This topic covers “Magnetism & Electromagnetism” of O Level Physics. (Equivalent to American high school diploma) If this is too basic for you, you can try the more advanced version here (Electromagnetism) and here (Electromagnetic Induction).

Simple Phenomena Of Magnetism

• Magnetism
• Properties Of Magnets
• Induced Magnetism & Electrical Method Of Magnetisation
• Magnetic field and magnetic field lines
• Temporary and permanent magnets
• Magnetic field due to current in a straight wire
• Magnetic field due to current in a solenoid

Applications of the magnetic effect of a current:

• Electric bell
• Circuit breaker

Force on Conductor in a Magnetic Field

• Force on current-carrying conductor
• Fleming’s left-hand rule
• DC motor

Electromagnetic Induction

• Electromagnetic induction and links with Faraday’s experiments
• A.C. generator
