- Oersted (1820): current makes a magnetic field.
- Field lines: N → S outside a magnet; closer lines = stronger field; they never cross.
- Straight wire: concentric circles — right-hand thumb rule. Solenoid: uniform field inside, like a bar magnet.
- Fleming's left-hand rule: First finger = Field, seCond = Current, thuMb = Motion (force).
- Domestic circuit: live (red), neutral (black), earth (green); fuse/MCB against overloading and short circuits.
For Class 10 (NCERT Science 10, “Magnetic Effects of Electric Current”). See also electromagnet and Ohm's law.
