Fields
Gravitational, electric and magnetic fields.
01Gravitational FieldsMapping g fields with F = GmM/r² and linking field strength to potential.Read lesson →02Electric FieldsUsing E = F/Q and E = V/d for point charges and uniform fields.Read lesson →03Magnetic FieldsFinding field patterns and the force F = BIl on current-carrying wires.Read lesson →04Potentials and EquipotentialsReading field strength from equipotential spacing and calculating work done.Read lesson →
