NAGALAND Class 12-science Physics Magnetism and Matter
Magnetic FieldMagnetic field, Oersted experiment, magnetic field due to current carrying straight conductor, circular coil and solenoid. Right hand thumb rule.
Magnetic PropertiesMagnetisation is defined as the magnetic dipole moment per unit volume.
Paramagnetic materials are feebly attracted and ferromagnetic materials are strongly attracted by magnets.
The lack of retraceability on applying a magnetic field to a ferromagnetic material is hysteresis.
