Overview
Electromagnetism explains the close connection between electricity and magnetism. A current-carrying wire produces a magnetic field, and a changing magnetic field can produce electric current. This chapter links the discovery of magnetic effects of current, the idea of magnetic field and flux, the f
Key Concepts
A compass needle placed near
A compass needle placed near a wire carrying current gets deflected. This showed that electric current produces a magnetic field and proved that elect
A magnetic field is the region
A magnetic field is the region around a magnet or current-carrying conductor where magnetic force acts. Its strength and direction can change from poi
Magnetic field lines are imaginary lines
Magnetic field lines are imaginary lines used to show the direction of magnetic field. The tangent at any point gives the field direction. Crowded lin
Magnetic flux is the number
Magnetic flux is the number of magnetic field lines passing through a plane of area A. For a plane at angle θ, flux is Φ = BA cosθ.
Magnetic flux density is the magnetic
Magnetic flux density is the magnetic flux passing through unit area perpendicular to the field. It is given by B = Φ/A. Its unit is tesla, and it is
