Magnetism

Every magnet has two poles

Every magnet has two poles—north and south—which cannot be separated. Like poles repel and unlike poles attract. Magnets show directive property (alig

A magnetic field is the region

A magnetic field is the region around a magnet where its influence can be felt. Magnetic field lines represent the direction and strength of the field

When a bar magnet (magnetic dipole)

When a bar magnet (magnetic dipole) is placed at an angle in a uniform magnetic field, it experiences a torque that aligns it with the field. The torq

Magnetic flux (φ_B) is the total

Magnetic flux (φ_B) is the total number of magnetic field lines passing through a surface, calculated as φ_B = B·A = BA cosθ. Gauss’s law states that

Magnetisation (I) is the magnetic moment

Magnetisation (I) is the magnetic moment per unit volume of a material. Magnetic intensity (H) is the external field applied to magnetise a material.
