Induced Fields
Magnetic fields may vary in time.
Experiments conducted in 1831 showed that an emf can be induced in a circuit
by a changing magnetic field.
Experiments were done by Michael Faraday and Joseph Henry.

Sources of the Magnetic Field
Magnetic Fields
The origin of the magnetic field is moving charges.
The magnetic field due to various current distributions can be calculated.
Ampres law is useful in calculating the magnetic field of a highly symm

Gausss Law
Gauss Law
Gauss Law can be used as an alternative procedure for calculating electric fields.
Gauss Law is based on the inverse-square behavior of the electric force between
point charges.
It is convenient for calculating the electric
