cs, electromagnetism and relativity. Historically they began at the time of Newton (seventeenth century) and were completed by Maxwell (nineteenth century) and Einstein (early twentieth century). Microscopic explanations began with J J. Thomson‘s discovery of the electron in 1897. For most physical phenomena 978-0-7102-0157-7978-94-011-7092-5

Handbook of Abductive Cognitionlectric current . in matter and introduce the concept of the magnetic field . sometimes called the magnetic induction field. The relationships between steady or magnetostatic fields having ∂./∂. = 0 and steady or direct electric currents having ∂./∂. = 0 are then developed and illustrated with examples.
